Answer: 30
Explanation:
From the question, the experimental probability that while at bat, Jessica will hit the ball is 2/5.
For a season if Jessica is at bat 75 times, the number of balls Jessica will be expected to hit will be the probability of her hitting the ball while at bat multiplied by the number of times she's at bat. Mathematically, this is expressed as:
= 2/5 of 75
= 2/5 × 75
= 150/5
= 30
Jessica is expected to hit the ball 30 times.
