Hello,
The spinner has total 5 numbers, and 2 even numbers:2,4
P(spinning an even number):
2/5
Now, flipping a coin
P(flipping heads): 1/2
To find the probability of Gary spinning an even number and flipping heads multiply 2/5 with 1/2 which equal 2/10 or 1/5. As a result, the probability of Gary spinning an even number and flipping heads is 1/5. Hope it help!
