The required probability is 9/98
Probability
Probability is the likelihood or chance that an event will occur.
For a two digits number with equal digits, the events are n(E) = {11, 22, 33, 44, 55, 66, 77,88, 99}
The total two natural numbers that we have are 98 in numbers.
Probability ( digits number with equal digits) = 9/98
Hence the required probability is 9/98
