Question 487103
spinner is spun 36 times.
it lands on A 6 times
it lands on B 21 times
it lands on C 9 times.


the empirical probability that it will land on A is equal to 6/36.
the empirical probability that it will land on B is equal to 21/36.
the empirical probability that it will land on C is equal to 9/36.


your answer is:


the empirical probability that it will land on B is equal to 21/36.


empirical means "from experience".


if something happens x% of the time from past experience, then you can say that the probability that it will occur again is x%.


that's exactly what we did above.


the x was 21
the total was 36.


x% would be 21/36 * 100 = 58.3% of the time.


the total percent should be equal to 100%.


you have:


p(A) = 6/36 = 16.7%
p(B) = 21/36 = 58.3%
p(C) = 9/36 = 25%


add them all up together and you get 16.7 + 58.3 + 25 = 100%
