Answer:
20 meters
Step-by-step explanation:
The shadow of the building will look like a right triangle. In this problem, the hypotenuse of the triangle is 25 meters, and one of the sides is 15 meters. What we are trying to find is the length of the other side.
We can do this by using pythagoreans theorem.
So, the last side (or the height of the building) is 20 meters.
Answer:
(a) P (U and V) = 0.
(b) P (U|V) = 0.
(c) P (U or V) = 0.83.
Step-by-step explanation:
Mutually exclusive events are those events that cannot occur at the same time. That is, if events A and B are mutually exclusive then,
<u>Given</u>:
Events U and V are mutually exclusive.
P (U) = 0.27 and P (V) = 0.56
(a)
As events U and V are mutually exclusive, the probability of their intersection will be 0.
That is,
Thus, the value of P (U and V) is 0.
(b)
The conditional probability of event B given A is:
Compute the value of P (U|V) as follows:
Thus, the value of P (U|V) is 0.
(c)
The probability of the union of two events, say A and B, is
Compute the value of P (U or V) as follows:
Thus, the value of P (U or V) is 0.83.
