Answer: 0.317
Step-by-step explanation:
Let A be the event that the selected household is prosperous and B the event that it is educated.
Given : P(A)=0.138, P(B)=0.261
P(A and B)=0.082
We know that for any events M and N ,

Thus , 

Hence, the probability P(A or B) that the household selected is either prosperous or educated = 0.317
Answer:
y=6
Step-by step: subtract 10 from 22 then divide it by 2 to get y.
2y+10=22
-10
2y=12
12/2=6
y=6
A. This question asks us to solve the equation for P. This also means to isolate this variable.
S=Ph+2B
S-2B = Ph
(S-2B)/h = P
B. Using the information, we plug this into the perimeter equation, where h = 4, S=96 and B = 8
(96-2(8))/4 = P
80/4 = P
P = 20 meters²
