Question

Bruno will spin the arrow on the spinner 2 times.

What is the probability that the arrow will stop on C at least once?

A. 19

B. 29

C. 13

D. 59

Answer 1

im taking the test right now and if you do any probability with 3 it will always have a 1/3 chance unless one side is more but in this case it isn't so you will have 1/3

Answer 2

P(C) = 5/9

Explanation:

To find the probability of at least one, we have to use the formula

P(at least one) = 1 - Probability of none

P(none) = 2/3

The number of times = 2

P(C) = 1- (2/3)^2

= 1 - 4/9

Now we have to simplify it.

P(C) = (9 -4)/9

P(c) = 5/9

The answer is P(C) = 5/9

Hope this will helpful.

Thank you.
