i have the following question which i cannot answer.
Ten Students A,B,..... are in a class. A committee of three is chosen at random to represent the class.
Find the following probabilities:
a) A belongs to the committee
b) B belongs to the committee
c) A and B belong to the committee
d) A or C belong to the committee
I dont have a clue on how to approach this question.
The are 10_C_3 combinations of choosing the members, but is that necessary?
thanks in advance.
