Step-by-step explanation:
hi
If 40% are boys, 60% are grills.
As fractions:
4/10 = 2/5 are boys
6/10 = 3/5 are grills
70% or 7/10 of the boys arrive by car:
(2/5)(7/10) = 14/50 = 7/25
And 60% or 3/5 of the grills arrive by car:
(3/5)(3/5) = 9/25
So in total we have 7/25 + 9/25 = 16/25 = 64/100 = 64%
64% chance that a child arrives by car.
Answer:
1/3
Step-by-step explanation:
11/12 -7/12 = 11-7/12 =4/12 =1/3
For days per gallon, divide 10g = 3d by 10
g = 3/10 days
1 gallon lasts 3/10 of a day
Have nice weekend
Answer:
No, because P(A) x P(B) ≠ P(A∩B)
Step-by-step explanation:
In order for two events to be independent, the following relationship must be held true:
In this example, we are given that, P(A) = 0.80, P(B) = 0.60 and P(A∩B) =0.40.
Therefore, P(A) x P(B) ≠ P(A∩B) and therefore the stock prices are not independent.
