Question

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

Answer 1

There are 12 letters in the mix and there are 3 letter A's. Therefore, the probability of drawing A of P(A) is:

a. a fraction in simplest form = 3/12 = 1/4
b. a decimal = 1/4 = 0.25
c. a percent = 0.25 *100% = 25%
