Question

Binomial Probabilities:

Suppose you go on a trip to Las Vegas. You stop at a slot machine where there is a 0.008 probability of winning the jackpot on a single turn. You decide to play the slot machine 2,000 times.  

For each problem, circle the appropriate numbers on the number line, then calculate the probability and round all answers to 4 decimals.   Make sure you write down what you entered into the calculator.

A. P(win exactly four times) = _________________                      0 1 2 3 4 5 6 7   ……. 2000

B. P(win at most five times) = _________________                       0 1 2 3 4 5 6 7   ……. 2000

C. P(win at least six times) = _________________                         0 1 2 3 4 5 6 7   ……. 2000

D. If you play the slot machine 2000 times, calculate the mean and standard deviation for the

       number of wins. Show your work.

            µ = __________                                                     σ = __________

                                                                                                     (round σ to 2 decimals)

E. If you play the slot machine 2000 times, would it be unusual to win 26 times?

     Use your answer from D to decide, then explain your answer using a complete sentence.
