A month of the year is randomly chosen. Find the probability that it has no more than 30 days, given that it starts with the letter A.

50% chance

The months that start with an A are April (30 days) and August (31 days) Because they ask "given that the month starts with A" it is conditional probability of 1 success (April) over the total Months that start with A.

1/2 =.50 or 50%
