Question

A number is selected at random from the first 35 natural number.what is the probability that it is either a multiple of 5 or a multiple of 7

Answer 1

n[s}=35
n{e}= multiple of 5=5,10,15,20,25,30,35=total=7
         mutiple of 7= 7,14,21,28,35= total=5
hence n{e}=7+5=12
so p{e}=n{e}/n{s}
             12/35
