So the prob of picking I the first time = 2/10 = 1/5
You are now returning it, so wouldn't the second draw have the same probability, since the letters certainly don't remember what happened to them ??
So what do you think?
A bag contains tiles with the letters A-R-I-T-H-M-E-T-I-C. Amelia chooses a tile without looking and doesn’t replace it. She chooses a second tile without looking. What is the probability that she will choose the letter I both times?
•1/25
•1/45***
•2/45
•2/55

I misread the part about replacing it
I read it as being replaced, so
it should be
(2/10)(1/9) = 1/45
you are right
