In a binomial distribution, n = 12 and π = .60. find the probability x=5

University of Phoenix must be an interesting School Subject! Unfortunately, I have degrees in English, history, and communication as my subjects. :(

To find the probability of X = 5 in a binomial distribution, where n = 12 and π = 0.60, we can use the formula:

P(X = k) = (n choose k) * (π^k) * ((1-π)^(n-k))

In this formula:
- (n choose k) represents the number of combinations of n items taken k at a time.
- π represents the probability of success for each trial.
- (1 - π) represents the probability of failure for each trial.
- k represents the number of successful trials.

Now, let's substitute the given values into the formula and calculate the probability:

P(X = 5) = (12 choose 5) * (0.60^5) * ((1-0.60)^(12-5))

To solve this equation, we'll need to calculate the combination (12 choose 5) first. The combination formula is given by:

(n choose k) = n!/((n-k)! * k!)

Substituting the values, we have:

(12 choose 5) = 12!/((12-5)! * 5!)

Calculating this combination will give us the value of (12 choose 5). Once we have that, we can calculate the probability using the complete formula.

I will calculate the combination and probability for you. Please wait a moment.
