During a recent season of baseball (MLB), Clayton Kershaw, the famous pitcher of Dodgers threw 2515 pitches. Of these pitches, 1303 were fastballs, 12 were changeups, 385 were curveballs and 815 were sliders.

a) The probability that Clayton Kershaw throws a fastball is
_____ %

Answer 1

The probability that Clayton Kershaw throws a fastball is calculated by dividing the number of fastballs by the total number of pitches, resulting in a probability of 51.77%.

Step-by-step explanation:

To find the probability that Clayton Kershaw throws a fastball, we need to divide the number of fastballs thrown by the total number of pitches. According to the given data, Kershaw threw 1303 fastballs out of 2515 total pitches.

Using the formula for probability:

P(Event) = Number of favorable outcomes/Total number of outcomes, we calculate the probability as follows:

P(fastball) = 1303 fastballs / 2515 total pitches = 0.5177

To express this as a percentage, multiply by 100:

P(fastball)% = 0.5177 × 100 = 51.77%

Therefore, the probability that Clayton Kershaw throws a fastball is 51.77%.
