There are 26 letters in the alphabet. If you select 2 different letters at random, what is the probability that you select J and P?

Answer 1

If ordering of selection isn't important (both selected simultaneously) - >

Total number of two letter selections = 26C2

Number of ways we can select J and P = 1

Probability of selecting J and P = 1/(26C2)

If ordering is important - >

Number of ways we can select J and P = 1 * 2 (J,P and P,J)

Probability of selecting J and P = 2/(26C2)
