Is getting exactly 10 questions correct the same probability as getting exactly zero correct? Describe the steps needed to calculate the probability of getting at least six questions correct if the student randomly guesses.
You do not need to calculate this probability! It would be greatly appreciated if you could show work as to how to solve these, thanks! Binomial probability: The probability of getting exactly x successes out of n trials, when the probability of getting 1 success in 1 trial is p is given by the formula.
Notice that is also written as nCx or C n,x or the number of combinations of n things taken x at a time. Put in numbers for n,p, and x. A multiple choice test has 10 questions. Although both are very unlikely, it is 3 times as likely to guess an answer incorrectly than to guess it correctly.
So it is more likely to guess them all incorrectly than all correctly. However, in a true-false test, they would be the same. You would do these steps: 1. Calculate the probability of getting exactly 6 correct.

I'm currently stuck on this question: A multiple choice test consists of 8 questions each with 4 choices. A student guesses the answers by choosing an answer at random.
We can't use binomcdf or anything like that to find the answer. The simplest way to do a is to find the probability of answering 0 or only 1 correctly, then subtracting that from 1. The probability any one of the seven is correct and the other 3 incorrect is that times 8, 0. The probability that either all 8 are incorrect or one is correct and the other 7 are incorrect is 0.
The probability of answer 2 or more correctly is 1- 0. Sign up to join this community. The best answers are voted up and rise to the top.

Community and Moderator guidelines for escalating issues via new response….Did you know they signed Eric Decker who has scored double-digit touchdowns in three of the last five seasons. What does all this mean. It means a Mariota vs Winston Super Bowl is forthcoming. Again, lots of value here. He tossed 28 touchdowns against only 2 interceptions, which was good enough to finish second behind Matt Ryan.
He deserves to be the frontrunner in 2017, and like his team is the clear-cut safe money. Rodgers is seeking a third MVP trophy and given the talented passing options at his disposal, he should have little trouble posting gaudy numbers once again. He also represents some of the best value on the board. Call it low risk, high reward. Carr has improved every season since entering the league in 2014. However, as with any quarterback, his MVP chances are directly tied to how well the Raiders play.
If they take a step back and miss the playoffs, Carr will undoubtedly shoulder some of the blame. Nevertheless, his price is tough to pass up. Ryan was worthy of his 2016 victory, but he kinda sorta won by default. The Falcons offense is poised to take a step back in 2017, so avoiding Matty Ice just makes sense. If the Bucs make a playoff charge, Winston will be the reason. He is still prone to poor decision-making, but his arm talent and fearless attitude are attributes needed in a franchise quarterback.
The fact that his odds are on par with Ryan and Carr is proof that his star is rising in the eyes of oddsmakers. No Zeke Elliott means more passing attempts for Dak. That could be good, or it could be bad.
Make no mistake about it, Prescott was impressive as a rookie. But a much tougher schedule and no Zeke to help alleviate pressure opens up the possibility of more errors in judgement for the second-year signal caller. A lot will have to go right for Dak to enter the MVP conversation.
DJ will need to rush for over 2000 yards and score 18 touchdowns to have a legit shot. And the Cards will have to make the playoffs.The figures he put out grabbed their attention, and Bell was invited onto CBS News, ABC News, and ESPN, quoted by the Wall Street Journal, Los Angeles Times, and the Associated Press. To this day, numerous outlets still say Bell provided the statistical evidence that broke the Donaghy story.
For example, Bell pointed out that Donaghy refereed 13 games during the 2006-07 season in which the margin fell within one point of the spread. Suchanek showed that this was what would be expected from random chance. But when asked by Suchanek to disclose the list of those games, Bell declined. You guys would rather a sober recitation of the facts. He encouraged first-time visitors to check out their many offers: Pregame Wire, Pregame Buzz, Free Picks from Pro Bettors, FreePicksByEmail, and Sportsbook Spy.
Waiting for them was an ocean of ads from sportsbooks and offers of generous sign-up bonuses. And maybe some surprises. Pregame would have to sell subscriptions and single-game picks by the truckload. Then I learned about the affiliate sheets. Based on the rates Bell was charging sportsbooks just to advertise on Pregame, the multimillion-dollar valuation seems logical.
At any one time, Pregame appeared to carry seven preferred sportsbooks. Just watch the money roll in. If tout services knew their customers were winning, the smart choice would be the one-time deposit, instead of one tied to losing.
The oddsmaker said he has never seen touts choose the deposit. After the Donaghy scandal, Bell and Johnny Detroit tried to make Pregame. So they funneled their sportsbook referrals through Canadian-registered Pregame Action, a go-between which may have provided a way around a U. Two months before Pregame Action went missing, Johnny Detroit left.
Johnny Detroit apparently recuperated quickly. There were rumors on sports betting forums that he and Karalis had asked to share in the affiliate spoils, but were rejected by Bell. Neither do I personally. It did not mention Pregame Action or Sharpbettor.Our prediction team always analyse the key facts of each team in full detail which allows our experts to then make the very best predictions on each soccer match based on those facts and figures.
