Calculate each probability.
What is the probability of landing on a consonant or a
yellow spot on the spinner above?
Since this is mutually exclusive (no consonants are on
yellow spots), then add all the favorable possibilities and
divide by the total:
Step 1: ☐ consonant(s) + ☐ yellow spot(s) = [
favorable
Step 2: ☐ favorable + ☐ total = (
%
• What is the probability of landing on a vowel or a red spot?
Since this is overlapping (a vowel is also on a red spot),
then add all the favorable possibilities, subtract off the
overlapping possibilities, and divide by the total:
Step 1: ☐ vowel(s) + ☐ red spot(s) - ☐ overlapping
=☐ favorable
Step 2: favorable + total =
