Answer:
0.8
Step-by-step explanation:
There are only 3 shirts that aren't blue or striped. He has 15 shirts, so the probability that he will pick a blue or striped shirt is 12/15. 12/15 as a decimal is 0.8.
I don't think it's D because 9 of the 15 shirts are striped, and it didn't ask specifically for green ones.
