Answer:
Step-by-step explanation:
Total number of marbles = 5 + 2 + 3 = 10
Probability of choosing 1 green marble = 2/10
Probability of choosing 1 yellow marble = 3/10
Notice (and this is important) that the denominator didn't change. Why?
Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.
So what is the probability of P(green then yellow)?
P(green then yellow) = 3/10 * 2/10 = 6/100
Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

Step-by-step explanation:
We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period
.
To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

Commutative property of multiplication states that we can multiply numbers in any order.
Upon switching the order while multiplying, we will get:

Therefore, our required equivalent expressions would be
and
.
Answer:
-4, 4
Step-by-step explanation:
The volume of a rectangular prism is:
V=xyz where x,y,z are the dimensions...
In this case:
V=5*(2 1/2)*(1 1/2)
which is equal to
V=(12 1/2)*(1 1/2)
So the top one and the third one down are the correct volume.
