Answer :
Number of students who play both baseball and basketball = 18+9+10-30 = 7
Probability that a student plays both sports = 7/30 = 0.233 = 23.3%
The probability that a student chosen randomly from the class plays both basketball and baseball is 7/30.
What is probability?
Probability is used to determine how likely it is that an event would happen. The likelihood of the event happens is between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
What is the probability that a student plays both basketball and baseball?
The number of students that play both games: 30 = 18 - n + 9 - n + 10 + n
Where n represents the number of students that play basketball and baseball
30 = n + 37
n = 37 - 30 = 7
Probability = 7/30
