Question:
Numbers 1 to 5 are written on separate slips, i.e. one number on one slip and put in a box. Wahida pick a slip from the box without looking at it. What is the probability that the slip bears an odd number?
(a) $\frac{1}{5}$
(b) $\frac{2}{5}$
(c) $\frac{3}{5}$
(d) $\frac{4}{5}$
Solution:
(c) Numbers on the slips are 1,2, 3, 4 and 5.
Odd numbers = 1,3, 5
Number of slips bears an odd number = 3
Probability that the slip bears an odd number $=\frac{\text { Numberofslipsbearsanoddnumber }}{\text { Totalnumberofslips }}$
$=\frac{3}{5}$
