Numbers 1 to 5 are written on separate slips
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 $=\frac{\text { Numberofslipsbearsanoddnumber }}{\text { Totalnumberofslips }}$

$=\frac{3}{5}$
