Question

I think I have the right answer, but I'm not sure. Is it possible if someone could just double check me?

Jean bought a bag of candy that contained red candies, green candies, and brown candies. Some candies are marked with a smile, and others are not marked. The probabilities are displayed in the table below:

Red Green Brown
Smile 0.10 0.30 0.10
No smile 0.20 0.15 0.15


If a random candy is chosen from this bag, what is the probability that the candy was red or had no smile?

0.60 <-- What I think it is.
0.20
0.30
0.50

Answer 1

prob red is 0.1+0.2
prob no smile is 0.20 0.15 0.15
we add (but we should *not* double count the red , no smile case)
in other words
0.1 + 0.2 +0.15+0.15
= 0.6

Answer 2

So I'm right?
