In order to the fourth player has the opportunity to bat, he/she needs that the three previous players make hit.
The joint probability of all three first batters make a hit is the product of their hitting percentages:
0.400 * 0.325 * 0.25
Pass the decimal numbers to fractions:
4/ 10 * 325/1000 * 25/100 = 32,500 / 1,000,000
Now simplify the fraction (divide numerator and denominator by 2500):
32,500 / 2,500 = 13
1,000,000 / 2,500 = 400
Then, 32,500 / 1,000,000 = 13 / 400
Answer: 13 / 400
