Question

A bag contains five green marbles, three blue marbles, two red marbles and two yellow marbles. One marble is drawn out randomly.

a) Are the four different colour outcomes equally likely ? Explain.

b) Find the probability of drawing each colour marble, i.e., P (green), P (blue), P(red) and P (yellow).

c) Find the sum of their probabilities.

Answer 1
