Allison created a table to help her represent the sample space of spinning a spinner and flipping a coin.


Result of spin

Result of coin toss Red Green Yellow Blue Purple
Heads Red, heads Green, heads Yellow, heads Blue, heads Purple, heads
Tails Red, tails Green, tails Yellow, tails Blue, tails Purple, tails

What is the probability that the result of the spin is blue and the coin lands heads up? (5 points)

two over ten

four over ten

five over ten

one over ten

The answer is one over ten. There is a total of 10 different outcomes in the sample space (5 colors on the spinner x 2 possible outcomes for the coin toss). Out of these 10 outcomes, only one is blue with the coin landing heads up: Blue, heads. Therefore, the probability is 1/10.
