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%

Respuesta :

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:

[tex]P(of\ an\ event) = \frac{\text{number of times the event occurs}}{\text{number of trials}}[/tex]

From given,

Number of times the event occurs = 20

Number of trials = 50

Therefore,

[tex]p = \frac{20}{50}\\\\p = 0.4[/tex]

In percentage,

[tex]p = 0.4 \times 100 = 40 \%[/tex]

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