Question

List all even numbers less than 50, then find the probability that a number selected at random is a multiple of 5

Answer 1

Below in bold.

Explanation:

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48.

There are 24 even numbers less than 50.

Of these 10 20 30 and 40 are multiples of 5 - a total of 4.

So the required probability is 4/24 = 1/6.

Answer 2

1/6

Explanation:

2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48

# of successful outcome = 24

a) a multiple of 5

(multiple of 5) = no of possible outcome/ no of successful outcome

= 4/24

= 1/6
