Answer:
No of white balls = 5
Step-by-step explanation:
Given that,
Total no of red balls = 4
Total no of green balls = 6
The probability of not drawing a white ball in one draw be, 
We need to find the number of white balls. Let there are x balls.
The probability of drawing a white ball = 1 - the probability of not drawing a white ball
= 1 -2/3
= 1/3
Using the formula for solving probability of having a white ball.

Hence, there are 5 white balls.
9,841.16x1.06^16= 25000.00739
B is the correct answer
Hi there.
If Michael wants to pay 20% of a $60 bill, he can find out how much to pay by using some multiplication.
60 · 0.2 = 12
Michael should pay $12 in tips.

%change=100(final-initial)/initial
%change=100(7498847290-6672678672)/6672678672
%change=12.38% (to nearest one-hundredth of a percent)
So the world's population increased by 12.38%.
