Answer:

43

Step-by-step explanation:

Total number of different colors = 7

Probability of spinner landing on blue = 1/7

Probability of spinner landing on green = 1/7

Probability of spinner landing on blue OR green = 1/7 + 1/7 = 2/7

if the spinner is spun 150 times,

Number of times spinner will land on green or blue = Probability of spinner landing on blue OR green x 150

= 2/7 x 150

= 42.85714...

= 43 (rounded to the nearest whole number)

Answer:

  • Approximately 43 times

Step-by-step explanation:

Number of sections is 7

Probability of each section is 1/7

Probability of blue or green:

  • P(blue or green) = 2*1/7 = 2/7

Spinner nun 150 times, number of stops on blue or green:

  • N = 2/7*150 = 42.86 ≈ 43 (rounded up)
