Probabilities are used to determine the chances of selecting a kind of donut from the box.
The probability that Warren eats a chocolate donut, and then a custard filled donut is 0.068
The given parameters are:



The total number of donuts in the box is:


The probability of eating a chocolate donut, and then a custard filled donut is calculated using:

So, we have:

Simplify

Multiply

Divide

Hence, the probability that Warren eats a chocolate donut, and then a custard filled donut is approximately 0.068

X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
18 divided by 6 is 3
when you add 3 with 4 it gives you 7
7 is your total answer
