Suppose that the sample space is s = {a, b, c, d, e, f, g, h} and that outcomes are equally likely. find the probability of the event e = {b, f, h}.

Event Space = {b, f, h}
Sample Space = {a, b, c, d, e, f, g, h}

There are 3 items in the event space out of 8 items in the sample space. Divide the two values to get 3/8

Optionally you can use long division or a calculator to convert to decimal form. Doing so gives 3/8 = 0.375

Also you can convert to percent form if your teacher wants you to. Simply move the decimal point to the right 2 spots to go from 0.375 to 37.5%




Summary:

Answer in fraction form is 3/8
Answer in decimal form is 0.375
Answer in percent form is 37.5%
