Question

A softball player got a hit in 20 of her last 50 times at bat. What is the experimental probability

that she will get a hit in her next at bat?

A.30%
B.40%
C.50%
D.60%

Answer 1

Option B

The experimental probability that she will get a hit in her next at bat is 40 %

Solution:

A softball player got a hit in 20 of her last 50 times at bat

To find: Experimental probability

The experimental probability is given as:

`P(of\ an\ event) = \frac{\text{number of times the event occurs}}{\text{number of trials}}`

From given,

Number of times the event occurs = 20

Number of trials = 50

Therefore,

`p = (20)/(50)\\\\p = 0.4`

In percentage,

`p = 0.4 * 100 = 40 \%`

Thus the experimental probability that she will get a hit in her next at bat is 40 %
