# Question

Use the probability function for three coin tosses as demonstrated on page 239 and verify the probabilities for x _ 0, 2 and 3.

## Answer to relevant Questions

a. Calculate P(4) and P(5) for Example 5.8 on page 249. b. Verify that the six probabilities P (0), P(1), P(2), . . . , P(5) form a probability distribution. Test the following function to determine whether or not it is a binomial probability function. List the distribution of probabilities and sketch a histogram. The survival rate during a risky operation for patients with no other hope of survival is 80%.What is the probability that exactly four of the next five patients survive this operation? Find the mean and standard deviation for the binomial random variable x with n _ 30 and p _ 0.6 using formulas (5.7) and (5.8). If the binomial (q _ p) is squared, the result is (q _ p)2 _ q2 _ 2qp _ p2 For the binomial experiment with n _ 2 the probability of no successes in two trials is q2 (the first term in the expansion), the probability of ...Post your question
