Answer:
Step-by-step explanation:
The fire department property is 2 units in height. 2 units from the line y=3 can be on the line y=5, or on the line y=1.
There are no answer choices with y=5, so the appropriate choices are those with C and D having the x-coordinates of B and A, respectively, and y=1.
C(1, 1), D(4, 1)
Answer:
P(B)=0.7
Step-by-step explanation:
When the events do not affect each other, they are known as independent events. In other words, two events are independent if the outcome of the second event is not affected by the outcome of the first event.
If A and B are independent events, the probability that both events will occur is the product of the probabilities that the individual events will occur:
P(A and B)= P(A)*P(B)
In this case, P(A and B)= 0.21 and P(A)= 0.30
Replacing:
0.21=0.30*P(B)
Solving:
<u><em>0.7=P(B)</em></u>
