Question

If pointer 1 is spun and then pointer 2 is ​spun, determine the probability of the pointers landing on a color other than yellow on the first spin and a color other than red on the second spin.

Pointer 1      Pointer 2

pointer 1 has 2 sections 50% red and 50% yellow.. pointer 2 has 3 sections 50% blue and 25% red and 25% yellow

Answer 1

P(color other than yellow on the first spin and color other than red on the second spin) = P(color other than yellow on the first spin) * P(color other than red on the second spin)

                                                      = (1 - P(yellow on first spin)) * (1 - P(red on second spin))

                                                      = (1 - 0.5) * (1 - 0.25)

                                                      = 0.375 (ans)
