What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Total number of players = 80
Number of players that they play all three sports = 31 (from the Venn diagram)
Probability that they play all three sports = 31/80
Thus, the probability that they play all three sports is 31/80 if the total number of students is 80 option first is correct.
