Question

Ex. 5. A box contains 25 tickets numbered 1 to 25. Two
tickets are drawn at random. What is the proba-
bility that the product of the numbers is even?​

Answer 1

Step-by-step explanation:

sample space n(s)=25

odd numbers tickets n(A)=13

even numbers tickets n(B)=12

probablity of odd Numbers= n(A)/n(S)

=13/25

probablity of even number=n(B)/n(A)

=12/25
