Assume that a procedure yields a binomial distribution withn=6 trials and a probability of success of p= 0.20. Use a binomial probability table to find the probability that the number of successes x is exactly 2. E Click on the icon to view the binomial probabilities table. P(2) = (Round to three decimal places as needed.)

In a survey, 63% of Americans said they own an answering machine. If 15 Americans are selected at random, find the probability that exactly 11 own an answering machine. Round the answer to at least four decimal places. P(11)= ?

A personal trainer at a gym is preparing a protein shake for a client after a work-out. The protein shake requires a 45 g serving of protein powder, to be taken from the 1.5 kg tub. If the tub in use is only partially full, and the amount remaining is unknown, what is the probability that there is enough protein powder left in the tub to make the protein shake? P(X > 45).___ Round to 3 significant digits.

use each described binomial probability distribution to calculate the cumulative probability requested. The probability of a high school student in America wearing jeans to school on a particular day is 40%. Leon stood by the doorway of his classroom and recorded whether the next 10 students who entered the classroom were wearing jeans.

While gathering eggs one day, Lisa has 15 eggs when Liana has 20 eggs at the moment when they started throwing them at each other. If 10% of the eggs are rotten, use the Binomial Distribution to calculate the probability that Lisa was hit by 3 or fewer rotten eggs from Liana.

determine whether the given procedure results in a binomial distribution. if not, give the reason. Rolling a single die 34 times, keeping track of the number of 3s that are rolled.

You host a house party with 4 guests attending. Every guest gets a chance to win a gift by spinning a wheel with 1/3 of a chance of stopping at the winning spot. If you prepare 2 gifts to give away, what is the probability of you being embarrassed for running short of gifts (i.e, there are more winners than the number of gifts). Round your answer to two decimal places (for example: 0.12)

Determine whether the given procedure results in a binomial distribution.    Tossing a coin 25 times and recording the number of tails you get.

Assume that a procedure yields a binomial distribution with n = 4 trials and a probability of success of p = 0.60. Use a binomial probability table to find the probability that the number of successes x is exactly 2. Click on the icon to view the binomial probabilities table. P(2) = (Round to three decimal places as needed.)

The probability that an event will happen isP(E)=0.22.Find the probability that the event will not happen.
