Answer: 3 delivers an hour
Step-by-step explanation:
9/3=3
blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
I think the answer is B.
6(-3)=-18, and y=2
so 6x-y=-18-2=-20
Answer:
D. 144km
