Answer:
P(A ⋃ B)=0.272
Step-by-step explanation:
A = the event that a random household is prosperous and
B = the event that it is educated.
From the survey, we are given:
- P(A) = 0.138
- P(B) = 0.216
- P(A ⋂ B) = 0.082
We want to determine the probability P(A ⋃ B) that the household selected is either prosperous or educated.
In Probability Theory:
P(A ⋃ B)=P(A)+P(B)-P(A ⋂ B)
P(A ⋃ B)=0.138+0.216-0.082
P(A ⋃ B)=0.272
The probability P(A ⋃ B) that the household selected is either prosperous or educated is 0.272
Answer:
NIce first question i will help you
Step-by-step explanation:
3 yards
CD is called the middle base and is equal to :(AB + EF)/2
CD = <span>(AB + EF)/2
4x = [(x</span>²+10) + (8-x)]/2
8x = x²+10+8-x
8x= x²-x+18
x²-9x+18 = 0
x' = [-b+√(b²-4.a.c)]/2a & x" = [-b-√(b<span>²-4.a.c)]/2a
x'= 6 and x" = 3, So we have2 values of x</span>
4x - 57 + 3x + 25 + 2x - 3 + 4x + 3x + 15 = 540
16x - 20 = 540
16x = 560
x = 35
hope this helped
