Basic Probability Concepts warm-up #1

You are flipping a coin and spinning the spinner shown. Identify the sample space

• R, O, P, Y, G, heads, tails

• heads, tails

• R, O, P, Y, G

• HR, HO, HP, HY, HG, TR, TO, TP, TY, TG

You are flipping a coin and spinning the spinner shown. What is the probability that you will get heads on the coin and red on the spinner?

• 0.50

• 0.10

• 0.20

• 0.90

The probability that it is going to rain tomorrow is 45% (0.45). What is the probability that is will NOT rain tomorrow? (HINT: the complement of this event)
