Answer:

a) P(A baseball pitch thrown with no strikes) = 0.3036

b) P(A baseball pitch thrown with fewer than two strikes) = 0.5402

Step-by-step explanation:

(a) What is the probability that a baseball pitch is thrown with no strikes?

We can calculate the probabilty as a relative frequency based on the data of the season.

The amount of pitches with no strike are 1060, out of a total of 3491 pitches.

Then, the probability is

[tex]P=1060/3491=0.3036[/tex]

(b) What is the probability that a baseball pitch is thrown with fewer than two strikes?

Here we have to add the events of no strikes (1060) and one strike (826).

[tex]P=\frac{1060+826}{3491}=\frac{1886}{3491}= 0.5402[/tex]
