There are 5 pens total; 3 of them red.
first draw probability red: 3/5
second draw probability red: 2/4
On the second draw there is one less red pen and one less total pens because they are not being put back into the pool of pens.
combined probability red then red (without replacement)
= (3/5) * (2/4) = 6/20 = 3/10
Answer:
The land area of Florida is 
Step-by-step explanation:
Let
x -----> the land area of Alaska in square miles
y -----> the land area of Florida in square miles
we know that
The linear equation that represent this problem is equal to
----> equation A
----> equation B
substitute equation B in equation A and solve for y

Remember that
Florida's land area is one-tenth the size of Alaska is the same as to say that Alaska's land area is ten times the size of Florida
