A game is played with a die having 11 sides numbered 1 to 11, each equally likely to turn up when the die is rolled. The player rolls the die, and wins if it stops with the uppermost face being in the set {2,6,7, 10, 11}. Let X be the random variable giving the number of wins if the die is rolled 4000000 times (i.e., 4 million times). (a) Explain why it is reasonable to assume that X has the binomial distribution. Equation Editor A. AI, BIU S x, x Styles Fant Size Words: 0 (b) Find the number of trials, the probability of a win on a single trial, the expected value of X and the standard deviation of X. In each case give your answer as an exact value - do not use decimals. Syntax advice. Enter your answers as exact values in Maple notation. You may enter expressions involving +.-. *./ and sqrt (square root) if needed, for example, (4+5* sqrt (6))/(7-8/9). Make sure you include all necessary brackets. Note that commas must not be used in large numbers, for example, type 1234567 and not 1,234,567. Answers: the number of trials is 4000000 the probability of a win is the expected value is E(X): the standard deviation is SD(X) = = (c) If the die is rolled 4000000 times, the probability that the number of wins is from 1817000 to 1820000 (inclusive) is given by a sum of the for b Pk> k-a where a, b are integers and p is an expression in the variable.
