Answer 1

Step-by-step explanation:

(a) multiple of 3= 8/25

(b) multiple of 3and5=1/25

(c) multiple of 5=5/25

Answer 2

Step-by-step explanation:

There are 25 number cards numbered from 1 to 25 in a box a card is dawn random, find the probability that the card is

(a)multiple of 3

Favourable outcome:{3,6,9,12,15,18,21,24}=8

Total outcomes= 25

$probability = \frac{8}{25}$

(b)multiple of 3 and 5

Favourable outcome:{15}=1

Total outcomes= 25

$probability = \frac{1}{25}$

(c) multiple of 5

Favourable outcome:{5,10,15,20,25}=5

Total outcomes= 25

$probability = \frac{5}{25} \\ \\ = \frac{1}{5}$
