Question

What is the probability that a number selected from the number 1, 2, 3, ..., 5 is a

multiply of 4?.​

Answer 1

1/5 is the required probability.

Step-by-step explanation:

Gien numbers are 1,2,3,4, and 5.

Multiples of 4 is 4 here.

So, Favourable outcome=1.

Total outcome= 5

$Required \ probability = \frac{Favourable \ outcome}{Total \ outcome} \\ = \frac{1}{5}$

Answer 2

Answer:

(i) What is the probability that a number selected from the number 1, 2, 3, ..., 5 is a multiply of 4?.

Numbers = 1,2,3,,4,5

Multiple of four = 4

Probability of occurrence of an event=Number of favourable cases/Total number of possible cases

= 1/5

(ii) What is the probability that a number selected from the number 1, 2, 3, ..., 15 is a multiply of 4?.

Numbers = 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15

Multiples of four = 4,8,12

Probability of occurrence of an event=Number of favourable cases/Total number of possible cases

= 3/15 = 1/5
