Question

An integer is chosen at random between 1and 100. Find probability of

Multiple of 8

Not multiple of 8

Answer 1

Total number of values divisible by 8 equals the integer of 100/8= 12
Or there are 12 numbers between 1 and 100 which are the multiples of 8 out of 100 numbers

So the probability of becoming the number a multiple of 8 when a number is selected from the numbers between 1 and 100
P(number multiple of 8)=12/100
=3/25

2)the remaining 88 numbers are not a multiple of 8
So
P(not a multiple of 8)=88/100
=22/25
