Question

find the probability of getting a factor of 36 if the numbers are 1, 15, 9, 7, 6, 4, 36 ,48, 18, 73

Answer 1

let s be the sample space of a random event

             n(s)= {1,15,9,7,6,4,36,48,18,73} 

          n(s)=10

n(E) ={36}=1...


               probability =n(E)/n(s)

                                   1/10
