What is that that’s not even a question
I believe it's the third one
It takes the faster pump 12 minutes to fill the tank.
Since the faster truck can produce 60% more than the other truck. 60% of 20 minutes is 12.
Answer:
n(B U S) = 75
Step-by-step explanation:
P(E) =
Let 'B' be the event of having twelve year old brother
Let 'S' be the event of having twelve year old sister
given data P(BUS) = 0.25
given total survey n(survey) = 300
we have to find the value is n(BUS) =?
we will use probability definition we get, P( BUS) =
substitute given values, we will get solution
after cross multiplication , we get
n(BUS) = 0.25 X 300
n(BUS) = 75
D. $1.00 each is the answer
