Probability of more than 3 = 0.25
Solution:
Given table shows the pitches, frequency and probability of pitches.
P(x = 1) = 0.15, P(x = 2) = 0.2, P(x = 3) = 0.4, P(x = 4) = 0.15, P(x = 5) = 0.1
To find the probability that the pitcher will throw more than 3 pitches.
Probability of more than 3 pitches = P(x > 3)
= P(x = 4) + P(x = 5)
= 0.15 + 0.1
= 0.25
P(x > 3) = 0.25
Hence the probability that the pitcher will throw more than 3 pitches to a batter is 0.25.
