Answer:
5/6
Step-by-step explanation:
First, list all the months of the year
January, February, March, April, June, July, August, September, October, November, December
There are 2 months that begin with the letter A : April and August
There are 12 months in the whole year
That leaves 10 (12-2) months that do not begin with the letter A
P(month that does not begin with A) = months that don't begin with A/ total
P(month that does not begin with A) = 10/12
The fraction can be reduced, since both the numerator and denominator can be divided by 2
P(month that does not begin with A) = (10/2) / (12/2)
P(month that does not begin with A) =5/6
