Ajar contains four blue marbles and two red marbles. suppose you choose a
marble at random, and do not replace it. then you choose a second marble.

find the probability if one of the marbles you select is blue and the other is red.

First we work out the probability that the first marble we select is blue.

To work this out, we divide the number of blue marbles by the total of marbles in the jar:

There are 4 blue marbles and 6 marbles altogether in the jar

So the probability of choosing a blue marble is:

------------------------------------------------------

Next we work out the probability of then choosing a red marble.

To work this out , we divide the number of red marble by the total of marbles in the jar:

There are 2 red marbles and there are 5 marbles in total

(remember - we have already taken out one blue marble, so there are only 5 marbles left in the jar)

So the probability of choosing a red marble is:

--------------------------------------------------

Finally, all we do is multiply the two probabilities together:

× =  =

------------------------------------------

Answer

 or (0.27 as a decimal)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
