(b) What is the probability that a randomly selected home run was hit to right field?

(c) Was it impossible for Mark McGwire to hit a homer to right field?

ANSWER:

Answer

Step 1 of 3

(a)

Mark McGwire of the St. Louis Cardinals hit 70 home runs.

Of the 70 home runs, 34 went to the left field, 20 went to left center field, 13 went to center field, 3 went to the right center field, and 0 went to the right field.

We are asked to find the probability that a randomly selected home run was hit to left field and also interpret this probability.

Hence the probability is 0.486, and there is a 48.6% probability that a randomly selected home run by McGwire went to left field.
