How many odd numbers are there from 1-9? How many numbers are there from 1-9? Thus, what is the probability of spinning an odd number on a spinner 1-9?
What's the probability of flipping a coin and having it land on heads?
Multiply the probability of these two to find your answer.

5 odd numbers
9 numbers
The probability of a coin landing on heads is 1/2. I don't get it.

So the probability of an odd number is 5/9
The probability of heads is 1/2
Now, you just multiply those two probabilities and get:
5/18
done!
