You mix the letters m, a, t, h, e, m, a, t, i, c, a, and l thoroughly. without looking, you draw one letter. find the probability p(a). write the probability as: a. a fraction in simplest form
b. a decimal
c. a percent

There are total 12 letters. 3 from them are the letter A.
The probability that the drawn letter is A can be calculated:
P(A)=number of events "letter A occurs"/ number of possible events that may occur 
P(A)=3/12
a. as a fraction: 3/12=1/4
b. as a decimal: 0.25
c. as a percent: 25%
