Find the value of x and y​

Part A:
The experimental probability of the coin landing heads up is 40%.
Work:
16/40=0.4
0.4•100=40
Since the coin in the experiment landed on heads 16 times out of 40 you divide 16 by 40 to get 0.4 and then multiply 0.4 by 100 to get 40%.
Part B:
Theoretically the probability of the coin landing heads up should be 50% because the coin has 2 sides.
Work:
40/2=20
20/40=0.5
0.5•100=50%
You take the number of flips and divide it by the possible options(heads or tails) and get 20. You the divide 20 by 40 and mutiply the answer by 100 to find the probability.
Hope this helps!
