Find P(3) when p = 0.80

Answer 1

For this question, you would want to use the formula

P(x)= (1 - p)^{x- 1} * p

We are now going to substitute x with 3 and p with 0.8

P(3) = (1 - 0.8)^{3- 1} * 0.8

Now we will solve the formula following PEMDAS

P(3) = (0.2)² * 0.8

P(3) =0.04 * 0.8

P(3) = 0.032

I hope this helps!
