8) A letter between U and I

Answer 1

Probability is a fraction.

It's the number of 'good' outcomes divided by TOTAL number of outcomes.

Answer 2

Perhaps an example would do you some good ^_^

For the first item, there are two 'good' outcome: A or B.
And there are 26 total outcomes, since there are 26 letters in all.

So the probability of the first item happening is:
\[\Large \frac2{26}=\frac1{13}\]

Answer 3
