The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 70/310
P(S) = 190/310
P(D and S) = 50/310
P(D or S) = P(D) + P(S) - P(D and S)
P(D or S) = 70/310 + 190/310 - 50/310
P(D or S) = 210/310 = 21/31
P(neither D nor S) = 1- 21/31
P(neither D nor S) = 10/31
The probability that a student chosen at random isn't in the drama club or the sports team is 10/31.
