Question

There are 6 marbles in a box with numbers from 1 to 6 on each of them.
(i) What is the probability of drawing a marble with number 2?
(ii) What is the probability of drawing a marble with number 4?
(ii) What is the probability of drawing a marble with a prime number?

Answer 1

There are 6 marbles with numbers 1 to 6.

(i) Probability = Number of favorable outcomes/Number of possible outcomes

    P(drawing a marble with number 2) = 1/6.

(ii) P(drawing a marble with number 4) = 1/6

(iii) P(drawing a marble with a prime number) = 3/6

                                                                             = 1/2

Hope this helps!
