2. A spinner is shown below for which outcome is NOT equally likely.

(E) If you spin the spinner once, what is the probability that it'll stop on A?
A takes up the same amount of romm that b and c do together. If you divide A in half, there would be 4 parts. Then there are 2 a's so, 2/4 or 1/2.
(A) If you spin the spinner once, what is the probability that it'll stop on B?
Again, A stands for 2 parts, so there are 4 parts all together. B takes up one of the 4 spots so, 1/4.
(T) If you spin the spinner 50 times, about how many times would you expect it to stop on A?
A takes up half of the room. Half of 50 equals 25. 25 is the answer.
(Y) If you spin 80 times, about how many times would you expect to stop on C?
C takes up a quarter of the room. A quarter is the same thing a as a fourth. 80 divided by 4 equals 20. 20 is the answer.
(MY QUESTION) If you spin the spinner 240, how many times would it supposedly stop on B?
240 divided by 4 equals 60 (24 divided by 4 equals six, add a zero at the end, voila!). Again B takes up a fourth of the space, and so forth, the answer is 60!
