If you spin the spinner 7 times, what is the best prediction possible for the number of times it will land on green?

3

Step-by-step explanation: let first consider a single spin.

Number of possible outcomes = 7

Number of required outcome = 4

Probability = 4/7

For the 7 times will be = 4/7 × 7 = 4

Standard deviation = root(4/7 × 3/7)

Standard deviation = 0.495

Standard error = root(7) × 0.495 = 1.3

The expected value = 4 - 1.3 = 2.7

Therefore, the expected value is approximately = 3
