consider a bowl containing 36 different slips of paper. Ten of the slips of paper each contain one of the set of digits 0 through 9 and 26 slips each contain one of the 26 letters of
the alphabet. Determine the probabilities of the events specified.
Drawing one slip, what is P(even number or a vowel)?
I know that there are four even numbers and five vowels. How do I figure this out?
so that would make it simply as
9/36 or 1/4
