Janice determined there were 10 possible outcomes when tossing two coins and spinning a spinner numbered 1 through 6. What is the correct number? What might have been Janice’s error?

Two coins have 4 possible outcomes: HH, HT, TH, and TT. The spinner has 6 possible results, so the total number of combined outcomes is 4 × 6 = 24. Choice C is correct; Janice may have added 4 and 6 instead of multiplying them.
