Answer:
P(beaver) = 0.33
Step-by-step explanation:
Spinner shown in the figure has 3 sections otter, turtle, beaver.
We have to find the probability P(beaver) in a single spin.
Total events n(S) = 3
and the favorable outcome in a single spin of spinner n(E) = 1
So as per rule of probability P(beaver) = 
Probability of getting beaver in one spin is 0.33
