Answer:
gfygou
Step-by-step explanation:
Carl has two more flips, and we want to know the probability that one and only one of those times it will be jelly side up. Assuming the basic heads/tails 50% probability each flip we have four possible outcomes: P P. P J, J P, J J, (btw P = plain side and J = Jelly side) and two of the four give us the one P wanted, so 2/4 = 50% probability.
