Joe has a bag of marbles. There are 2 purple, 1 red, and 3 green marbles in the bag. Joe selects a marble, does not replace it before selecting a second marble. What is the probability that Joe will select a green marble, then a red marble?

1/10

Step-by-step explanation:

There are 6 marbles in the bag. 3 out of 6 are green.

3/6 = 1/2

So, he has a 1/2 of picking a green marble.

After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.

Since there’s one red marble in the bag the chance of trying one is 1/5.

Now to find the chance or drawing a green and red marble you need to do the equation:

1/2 x 1/5

This equals 1/10.

The probability is 1/10

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
