# ) You are performing 7 independent Bernoulli trials with p = 0.4 and q = 0. Calculate the probability of the stated outcome. Check your answer using...

1.) 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.)

At least three successes

P(X ≥ 3) =

2.) You are performing 5 independent Bernoulli trials with p = 0.1 and q = 0.9. Calculate the probability of the stated outcome. Check your answer using technology. (Round your answer to five decimal places.)

No failures

P(X = 5) =

3.) In the exercise, X is a binomial variable with n = 4 and p = 0.1. Compute the given probability. Check your answer using technology. HINT [See Example 2.] (Round your answer to five decimal places.)

P(X ≤ 2)

4.) In the exercise, X is a binomial variable with n = 5 and p = 0.2. Compute the given probability. Check your answer using technology. HINT [See Example 2.] (Round your answer to five decimal places.)

P(X = 3)

5.) The probability that a randomly selected teenager watched a rented video at least once during a week was 0.65. What is the probability that at least 7 teenagers in a group of 9watched a rented movie at least once last week? (Round your answer to four decimal places.)

P(X ≥ 7) =
