Answer:
The correct answer is 0.5.
Step-by-step explanation:
The probability of a spinner landing on the shaded part follows binomial distribution.
Equation to be used is P(r) = ×
×
, where n is the number of times the spinner is spun and r is the number of times the spinner falls on the shaded region.
The probability of the spinner landing on the shaded part is p = . The probability of it landing on the unshaded part is q =
.
The spinner is spun n = 3 times.
We need to find the probability of it landing on the shaded part r = 2.
∴ Putting the values in the equation gives,
P(r) = ×
×
= 3 ×
×
= 0.5
