Question

The table shows the batting records for members of a softball team. Use the table to find each experimental probability.

A. The probability that Juanita gets a hit.
B. The probability that Su does not get a hit.

Player:
Sherise, Lena, Su, Juanita
Number of hits:
Sherise: 10
Lena: 7
Su: 14
Juanita: 20
Times at bat:
Sherise: 17
Lena: 11
Su: 24
Juanita: 31

Answer 1

A. 20/31

B. 5/12

Explanation:

A. P(Juanita hits) = 20/31

B. P(Su doesn't hit) = (24-14)/24 = 10/24 = 5/12

Answer 2

The probability that Juanita gets a hit is 0.645 and the probability that Su does not get a hit is 0.417.

Sure. The probability that Juanita gets a hit is 0.645 and the probability that Su does not get a hit is 0.417.

Player Number of hits Times at bat Probability of getting a hit

Sherise 10 17 0.588

Lena 7 11 0.636

Su 14 24 0.583

Juanita 20 31 0.645

The probability of getting a hit is calculated by dividing the number of hits by the times at bat. For example, the probability that Sherise gets a hit is 10 hits ÷ 17 times at bat = 0.588.

The probability of not getting a hit is 1 minus the probability of getting a hit. For example, the probability that Su does not get a hit is 1 - 0.583 = 0.417.
