There are 8 tiles

Total possible outcome = 8

The formula oof probability is


\text{Probability}=\frac{\text{required outcome}}{total\text{ outcome}}

There is one A tile in the bag

If an A is selected first from the bag, the probability of picking an A is


P(A)=(1)/(8)

If a first "I" is pulled first from the bag, the number of tiles will be 7

The total outcome becomes 7,

The probability of selecting an A after the first I is pulled from the bag will be


P(A)=(1)/(7)

From the result of both probabilities,

The probability of selecting of selecting an A after an I is pulled from the bag increase from 1/8 t0 1/7

Hence, the probability of selecting an A increases after the first I is pulled from the bag.
