No failures
P(X = 5)=

In the exercise, X is a binomial variable with n = 3 and p = 0.3. Compute the given probability. Check your answer using technology. HINT [See Example 2.] (Round your answer to five decimal places.)
P(X ? 2)=

The probability that a randomly selected teenager watched a rented video at least once during a week was 0.7. What is the probability that at least 7 teenagers in a group of 9 watched a rented movie at least once last week? (Round your answer to four decimal places.)
P(X ? 7)=

You are performing 7 independent Bernoulli trials with p = 0.4 and q = 0.6. Calculate the probability of the stated outcome. Check your answer using technology. (Round your answer to five decimal places.)
