For the spinner above, the probability of landing on black is 1/2 and the probability of landing on red is 1/3. suppose is is spun four times. what is the pobability that it will land on white all four times?
a. 1/216
b. 1/24
c. 1/4096
d. 1/1296
my answer was a. 1/216 but, that was wrong. cant figure this out. i always hated doing probability

First, we need to figure out the probability of landing on white one time. The probability of landing on black is 1/2, and the probability of landing on red is 1/3. If we add these probabilities together we get:



So if there is a 5/6 chance of NOT landing on white, then there must be a 1/6 chance of landing on white.

To find the probability of landing on white 4 times, multiply 1/6 to itself 4 times.



The answer is D.
