Al tosses one quarter and at the same time Betty tosses two quarters. What is the probability that Betty gets the same number of heads as Al?

This is what I have:

Al H/T ½ 50%

Betty HH / HT / TH/ TT ½ 50%

The probability is ½ or 50% chance that Betty will get the same amount of heads as Al

Can you see if I'm on the right track or can you guide me to the right track
