Good evening! I have a question it is considering a binomial probability distribution with p=0.35 and n=8 determining the following probabilities:

a) Exactly three successes

b) Less than three successes

c) 6 or more successes

However, I am wondering how do you input these calculations in your calculator?

For Example:

a) P(x=x)= (8 3) (0.35)^3(0.65)^5=0.2786

How exactly is this calculation put into the calculator I have tried numerous times to reach this answer and I am way off. Please help
