Answer:
The probability of getting 3 successive 1's from spinning the spinner 3 times = 0.027
Explanation:
The spinner has 4 sides, 1,2,3 and 4
The probability of landing on a 1 = P(1) = 0.3
The probability of landing on a 2 = P(2) = It isn't given
The probability of landing on a 3 = P(3) = x
The probability of landing on a 4 = P(4) = 0.1
If Denzil spins the spinner 3 times, what is the probability of getting 3 successive 1's?
Noting that each spin is independent from one another, the probability of getting 3 successive 1's from spinning the spinner 3 times is given as
P(1) × P(1) × P(1) = 0.3 × 0.3 × 0.3 = 0.027
Hope this Helps!!!
