Answer:
Probability that Caroline buys fruit, a CD or both is 0.76.
Step-by-step explanation:
Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.
Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.
Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.
Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.
Answer:
Total number of cups in package are 2400.
Step-by-step explanation:
Given : An economy package of cups has 720 green cups.
And the green cups are 30% of the total package.
We have to find the number of total cups in the package.
Let the package contain x cups in total.
Given: green cups are 30% of the total package that is 30% of x,
Also , given package has 720 green cups.
Thus, 30% of x = 720
Solving for x, we have,
Thus, total number of cups in package are 2400.
Answer:
2 and 6 for the circles.
-18 for the square.
Step-by-step explanation:
-3 times a number is -6.
The number is 2.
2 times a number is 12.
The number is 6.
6 times -3.
The number is -18.
The answer is b
Its b because you distributed
4(4a+5)
You multiplied 4x4a and you got
16a+4(5)
Which 4x5 is 20
So its 16a+20
Answer:
0.04 gallons in one mile
Step-by-step explanation:
Basically, you lose 2 in 50 miles. So in order to figure out how many you lose in one mile, you would take 2/50, which would give you 0.04.
