Step-by-step explanation:
what math do u do or not do if that makes since
Answer:
1. $58650
Step-by-step explanation:
The probability of drawing a purple piece during the first class is 7/25 because 7 pieces of paper are purple out of a total of 25 pieces of paper
Since all pieces of paper are returned, the probability of drawing a blue piece during the second class is 2/25 since there are 2 blue pieces out of a total of 25 pieces of paper
The wording is meant to trick you here. If the purple paper from the morning was not replaced before drawing the probability of drawing a blue piece in the second class would increase.
Always remember to reduce fractions where you can
To compare whether or not two fractions are equivalent, they must have the same denominator.
What is a common denominator you can make between
and
? Some possible options are 5n or 10n.
I'll make both denominators 5n:1)
already has 5n in the denominator.
2) To get 5n in the denominator for
, you want to divide both the numerator and denominator by 2 (same as multiplying top and bottom by
). Since you're doing the same thing to the numerator and denominator, you are not changing the value of the fraction:
Now
compare the two fractions. Since
, your fractions are equivalent!
