Q.2 There are 6 marbles in a box with numbers from 1 to 6 marked 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 5?
Answer :

(i) Total number of marbles marked with the number from 1 to 6 = 6 Therefore n(S) = 6 Number of marble marked with 2=1 Therefore n(E) = 1 Therefore Required probability = \(\frac{n(E)}{n(S)}=\frac{1}{6} \) (ii) Number of marble marked with 5 = 1 Therefore n(E) = 1 Therefore Required probability = \(\frac{n(E)}{n(S)}=\frac{1}{6} \)
