Question

Letter tiles similar to the example here are placed in a bag. There are a total of 8 tiles in the bag containing the following letters: G, I, R, V, 1, A, I and NDoes the probability of selecting an A increase or decrease after the first "I" told is pulled from the bag?

Answer 1

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.
