The teacher has 3 red pens 8 black pens and 4 blue pens all the same size in his box what is the probability of reaching in without looking and picking out a red pen 1/3
1/15
1/4
1/5

1/5

Step-by-step explanation:

So we have a total of 15 pens and 3 of those pens we know are red. The probability of randomly selecting a red pen would be 3/15 or simplified 1/5

1/5

Step-by-step explanation:

** numbers of chances you can pick/total chances of that you can pick anything

--> # of chances you can pick red pens, in this case, is 3, since there are only 3 red pens -->3/total

--> in this case total should be every numbers of pens added --> 3+8+4 = 15

--> 3/15 -->simplify: 1/5
