7/7.42 = $0.94
Hope this helped :)
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
Answer:
0.4437
Step-by-step explanation:
First we will define independent events.
Two events are said to be independent when the occurrence of one event doesn't affect the probability of occurrence of second event.
Given
P(Q)=0.87
and
P(R)=0.51
The probability of independent events is given as:
P(Q∩R)=P(Q)*P(R)
=0.87*0.51
=0.4437
So the probability of Q and R is 0.4437 ..
This can be expressed by,
80 + 40 + 20 + 10 = 150
