Answer:
The probability is [tex]P(X = 3) = 0.40[/tex]
Step-by-step explanation:
From the table the frequency of 3 pitches is [tex]f_3 = 40[/tex]
The total frequency is [tex]f_t =15 + 20 + 40 + 15+10 = 100[/tex]
The probability that the pitcher throw exactly 3 pitches to a batter.is
[tex]P(X = 3) = \frac{40}{100}[/tex]
[tex]P(X = 3) = 0.40[/tex]
