3. Points A, B, C, D, and E represent points on an interstate highway.
A B C D E
If a random accident occurs on AE, find the
probability that it will occur between B and C. BC 8
P(accident is in BC) = = AE 8
P(accident is in BC) =
= 0.16
= 16 % 50

4. Find the probability that the spinner will land
on region D.
degrees in D A B
P(D)=
