very basic probability question
I was just confused if I am thinking this one right.
so the question is:
"In a set of numbers from 1 to 10. If two numbers are to be selected from these 10 numbers with replacement, then what is the probability that at least one of them is even?"
So I thought. there are four possible outcome,
and since 3 out of them contains even number So I thought the probability
was 3/4. Is this the right way of thinking this problem??
please help. thank you.
