In the past, Ben has been able to hit a baseball at the batting cage 20% of the time. He decides to head back to the batting cage. (a) What is the probability that his first hit will be on the eighth pitch? (b) What is the probability that his first hit will not be within the first nine pitches? *

(4/5)^7 x 1/5

Step-by-step explanation: This is a geometric probability distribution. The probability of a success is 20% = 1/5 and the probability of a failure is therefore 4/5.

We want to know the probability that Ben is successful on the eight attempt. This means he has failed the first 7 times but succeeds on the 8th try.

So probability is (4/5)^7 x 1/5

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
