Answer:
1. The probability that B occurs or A does not occur (or both) is 0.73.
2. The probability that either B occurs without A occurring or A and B both occur is 0.73.
Step-by-step explanation:
It is given that the events A and B are mutually exclusive. It means the intersection of A and B is 0.
Given information:
We get,
(1) We need to find the probability that B occurs or A does not occur (or both).
Therefore the probability that B occurs or A does not occur (or both) is 0.73.
(2) We need to find the probability that either B occurs without A occurring or A and B both occur.
Therefore the probability that either B occurs without A occurring or A and B both occur is 0.73.

Answer:4/7
Step-by-step explanation: You find the common denominator, which is 84 and get 35/84 and 48/84.
To solve Az + 17 = -4z - b for z, we begin by combining like terms. We get:
Az + 4z = -b - 17, or z(A+4) = -(b+17).
Dividing both sides by (A+4), we get:
-(b+17)
z = --------------
A+4
