Ответ:
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
(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).
