Question

an integer is chosen at random between 1 and hundred find the probability that it is not divisible by 8​

Answer 1

answer-

number divisible by 8 below 100= till 96

8*12= 96

so nimbers not divisible by 8 till 100 = 100-12=88

so probability= 88/100

= 22/25

hope it helps

have a nice day

Answer 2

Answer:

the numbers which are divisible by 8 in 1 to 100 are 8,16,24,32,........,96

the number of numbers that divisible by 8 are 12

therefore probability of divisible by 8 is 12/100

= 3/25

then the probability of not divisible by 8 is

= 1- (3/25)

= (25/25) - (3/25)

= (22/25)
