Question

an integer is chosen between 0 and 100. what is the probability that it is
(1)divided by 7
(2)not divided by 9

Answer 1

I think answer is not divide by 9

Answer 2

There are 14 multiples of 7 from 1 to 100.
So probability that the no. is divisible by 7 is
14/100= 7/50
There are 89 nos. not divisible by 9 from 1-100.
So, probability of getting a no. not divided by 9 is 89/100.
So, the answers are-
(1) 7/50
(2) 89/100
