Answer:
0.28.
Explanation:
It is given that a baseball player hit the ball 42 times out of the last 150 times at bat. 
Total no of times he bat = 150 
No. of times he hit the ball = 42 
We need to find the player's experimental probability of getting a hit the next time at bat. 
 
 
 
 
 
 
Therefore, the required probability is 0.28.
