A spinner has 12 equal sectors: 4 red, 3 blue, and 5 yellow. The pointer on the spinner is spun 3 times. What is the probability of landing on red, then blue, then red again?

Sagot :

Probability is defined by (the number of favorable outcomes)/(the number of possible outcomes)

Fisrt spin: 4 / 12 = 1/3
Second spin: 3 / 12 = 1/4
Third spin: 4 / 12 = 1/3

Multiply: 1/3 * 1/4 * 1/3 = 1/36 or 2.78%
