4) In Toronto, Canada, 55% of people pass the drivers' road test. Suppose that 100 peopletake the test.a) What is the number of people who are expected to pass?b) What is the standard deviation for the number expected to pass?c) What is the probability that less than 50 passed?d) What is the probability that at least 49 passed?e) What is the probability that at most 45 passed? 2) Based on previous data, a probability distribution was constructed to use probability thata certain soccer team scores a certain number of goals. Let X is the number of goalsscored in a game:13P(X)0.180.340.350.02a) Find the value of the missing cell in the probability distribution.b) Find the expected number of appearance defects. Interpret your answer.c) Find the standard deviation. Interpret your answer.
