Alan works as a cashier at a general store. He has a 9% chance of pulling out a 2004 quarter from his drawer.

He wants to know the probability that it takes at least four attempts to pull out a 2004 quarter.

Which simulation can best be used to compute the probability?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

kekdkdkccc

so

step-by-step explanation:

kekdkckcldlx

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

answer:

1.14285714286

step-by-step explanation:

divide 40 into 35 and you will get your answer
