Question

1. A spinner has four colors: red, yellow, green, and purple. The experimental probability of spinning a red is 0.2, of spinning a yellow is 0.3, and of spinning a green is 0.4. If the spinner was spun 30 times, how many times did it land on purple? Show all steps and explain please.

Answer 1

THe probability of purple is 1 - (0.2+0.3+0.4) = 1 - 0.9 = 0.1

0.1 * 30 = 3
