Answer:

0.81

Step-by-step explanation:

P(success) = 0.9

P(failure) = 1 - 0.9 = 0.1

Binomial probability:

P(X=n) = nCr (0.9)^n (0.1)^r

Here, n=2 and r=0:

P(X=2) = ₂C₀ (0.9)² (0.1)⁰

P(X=2) = 0.81

X is the number of free throws made  P(X = 2) is  0.81

What is probability?

Probability is a branch of mathematics that deals with the occurrence of a random event.

calculation:-

⇒P( sucess event ) = 0.9

⇒P(failure event) = 1 - 0.9 = 0.1

Binomial probability:

    P(X=n) = nCr (0.9)ⁿ (0.1)ˣ

      let, n=2 and r=0:

          P(X=2) = ₂C₀ (0.9)² (0.1)⁰

                P(X=2) = 0.81
