ANSWER
60 possible outcomes
Step-by-step explanation
If he spins the 3-section spinner, there are 3 possible outcomes: Walk, Run, Stop.
If he spins the 4-section spinner, there are 4 possible outcomes: red, green, blue, orange.
If he spins the 5-section spinner, there are 5 possible outcomes: Monday, Tuesday, Wednesday, Thursday, Friday.
If he has to spin the three spinners, the total possible outcomes is the product of the possible outcomes of each spinner: 3x4x5 = 60.
