Aspinner of a board game can land on any one of three regions labeled: a, b, and c. if the probability the spinner lands on b is five times that offive times that of a, and the probability the spinner lands on c is three times that ofthree times that of a, find the probability the spinner lands on a.

1/9

Step-by-step explanation:

Let's call x the probability of landing in A

So, probability of landing on B is 5x and probability of landing on C is 3x.

As we only have this options, the probabilities A + B + C = 1. So,

x + 5x + 3x = 1

9x = 1

x = 1/9

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
