Question:

One ticket is drawn at random from a bag containing tickets numbered 1 to 40. The probability that the selected ticket has a number which is a multiple

of 5 is

(a) $\frac{1}{5}$

(b) $\frac{3}{5}$

(c) $\frac{4}{5}$

(d) $\frac{1}{3}$

 

Solution:

(a) Number of total outcomes = 40

Multiples of 5 between 1 to 40 = 5,10,15,20,25. 30 35, 40

$\therefore$ Total number of possible outcomes $=8$

$\therefore$ Required probability $=\frac{8}{40}=\frac{1}{5}$
