Step-by-step explanation:
Answer:
P(B and D) = 0.35
Step-by-step explanation:
It is a probability tree diagram. Here to find P(B and D):
apply method:
P(A and B) = P(A) × P(B)
Here given:
So, P(B and D):
A = fruit juice 40%
B= 90% juice
then
30 gallons + A = 55• C/100
30 gallons + N • (40/100) = (30 + N)• (55/100)
Now solve this equation, for N
3000 + 40N = (30+N) •55
then
3000 - 1650 = 55N - 40 N = 15N
1350 = 15 N
then
N= 1350/15 = 90
Then answer is
Should be mixed 90 gallons of 40% fruit punch
