Albert wants to buys some pens. He is comparing 4 different packs of pens. The number of pens in each pack and the cost of the pack is shown in the table below. Which two packs of pens have the same cost per pen?

There are 2 red pens in each pack

There are 3 blue pens in each pack

Step-by-step explanation:

we know that

270=2*3^{3} *5

180=2^{2}*3^{2}*5

Find the Greatest Common Factor (GCF)

The GCF is equal to> 2*3^{2}*5=90

the greatest number of packs she can make is 90

Find the number of red pens in each pack 180/90=2 red pens

Divide the total number of red pens by the total number of packs

Find the number of blue pens in each pack 270/90=3 blue pens

Divide the total number of blue pens by the total number of packs

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
