Apharmacist receives a shipment of 22 bottles of a drug and has 3 of the bottles tested. if 5 of the 22 bottles are contaminated, what is the probability that exactly 1 of the tested bottles is contaminated?

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.

Step-by-step explanation:

is the number of different combinatios of x objects from a set of n elements, given by the following formula.

In this problem, we have that:

Total number of combinations:

Desired combinations:

It is 1 one 5(contamined) and 2 of 17(non contamined). So:

What is the probability that exactly 1 of the tested bottles is contaminated?

There is a 44.16% probability that exactly 1 of the tested bottles is contaminated.

1/800 is the right answer

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
