Answer:
Theoretical Probability: 1/2
Actual Probability: 17/40
Step-by-step explanation:
When you toss a coin, it can land on one of either Heads, or tails. This is a 1 out of 2 (or 1/2) chance of each happening. This is the theoretical probability, since real life will most likely not follow this exactly, as shown by the tests in the question.
In the question, it says that it landed on heads 17/40 times, meaning that the probability is 17/40.
