Elenna [48]

Answer:

A baseball player hit 73 home runs in a season.

Of the 73 home​ runs, 25 went to right​ field, 25 went to right center​ field, 8 went to center​ field, 10 went to left center​ field, and 5 went to left field.​

(a)  the probability that a randomly selected home run was hit to left center ​field = \frac{10}{73}=0.1369 = 13.69%

(B) Since the probability of an unusual event is 0, it was possible for this player to hit a home run to left center ​field.

Solnce55 [7]
We need to make them all equivalent, so when all denominators are equal, we can see. 1/2 is 50/100, 3/5 is 60/100, and 99/100 stays the same.
The biggest is 99/100.
