(b) What is the probability that the letter of a month selected is a consonent? Also write notes explaining how the concept of probability is used in estimating different weather or climate forecasts?

Answer 1

Months no.of times

J 3

F 1

M 2

A 2

S 1

O 1

D 1

a)No .of letters=12=n(s)

No.of vowels=3=n(E)

Probability =n(E)/n(S)

=1/4

b)No .of constants=9=n(E)

probability =9/12=3/4
