Question

A boy is asked to say a two digit number which is less than 50. What is the
probability that the boy says a number whose ten's digit is greater than the
one's digit?

Answer 1

hey

Total no.of possible outcomes = 50

No.of favourable outcomes = 10

P (E) = no.of favourable outcomes / total no.of possible outcomes

= 10/50

= 1/5
