Question

Use the binomial probability to solve.

Basketball Suppose you make 90% of your free throws and you attempt 3 free throws. Use the Binomial Theorem to calculate each probability.

a. You do not make any of them.
- I have this one
b. You only make 1 of them.
- I have this one
c. You only make 2 of them.
- I don't understand this one
d. You make all of them.
- I don't understand this one

Answer 1

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

c. .9 * .9 * (1-.9) = ?

d. .9^3 = ?

Answer 2

So....

c. .9*.9*(1-.9)=-0.09
d. .9^3=0.729

would that be correct?
