Question

An integer is chosen at random between 1 and 100. Find the probability that it is.
(i) divisible by 8.
(ii) not divisible by 8​

Answer 1

Answer:

(i) P(divisible by 8)= 12/100

(ii) P(not divisible by 8)= 88/100

Step-by-step explanation:

(i) P(divisible by 8)= 12/100 , {8,16,24,32,40,48,56,64,72,80,96}

(ii) P( not divisible by 8)= P(divisible by 8) Compliment= 1-12/100

= 88/100

Answer 2

Answer:

Total no.of integers=100

Total no.of integers divisible by 8=12

8,16,24,32,40,48,56,64,72,80,88,96

Probability of getting integers divisible by 8=12/100=3/25

Probability of getting integer not divisible by 8= 1- Probability of getting integers divisible by 8

=1-3/25

=25-3/25

=22/25
