EXCEL is used to find the binomial probabilities.

P(3<X<5) should be calculated.

Four lies between 3 and 5.

P(3<X<5) = P(X=4)

Click on Formulas -> Insert Function -> BinomDist

For Number_s we enter 4

For trial which is the number of trials we enter 8

For Probability_s the probability of success is 0.32

For Cumulative we enter 0

P(3<X<5) = 0.15694
