Step 1
In this case, there are two possible outcomes for each trial, classified as a success (Favor), or as a failure (Not favor). Hence, this condition is met to use the binomial model. There is a fixed number of trials, hence a binomial model can be used for this case.
The formula of binomial is,
(a)
The probability P(X=3) can be calculated as:
P(3) = 0.224 |
