Mathematics: Corbin has pens. There are three types of pens: red, black, and blue. If the probability of getting a red pen is 4/10 and the probability of getting black is 5/10, what is the probability of getting blue? ( I really need this answered or else I might not pass this year pls help! simplify if u can. Hint: It ll be a fraction, I know this because I have to match the fraction to the problem. For whoever helps me I m forever grateful and thanks so much!)

blue=1/10

Step-by-step explanation:

so there are 3 types of pens

Red = 4/10

black= 5/10

blue=?

so u add up the other 2 fractions - 4/10+5/10 to get 9/10

then u see how many Corbin would have left: 1/10

1/10= that the amount of blue pens he has.
