Answer:
<h2>

</h2>
Step-by-step explanation:
The probability of occurring the event A is
.
The probability to occur the event B is
.
It is also given that the events are independent that is they do not depends on each other.
So, the probability of occurring both the events simultaneously can be get by simply multiplying the probabilities of both the events.
Hence, the probability is

Answer:
For X, the parameter
is λX = 1/2 and for Y it is λY = 1. Using the formula sheet, Mean is
E[Z] = E[X] + 2E[Y ] = 4. Variance is V ar(Z) = V ar(X) + 4V ar(Y ) = 8.

Step-by-step explanation:
4(y - 7) = 2y - 38
4y - 28 = 2y - 38
4y - 2y = -38 + 28
2y = -10
y = -5
