Question

Maria flips a coin 20 times. The coin only lands on tails 9 times. According to theoretical

probability how many more times would Maria have expected the coin to land on tails?

Answer 1

1

Explanation:

A coin only has two outcomes. Meaning that she has a 50/50 chance of landing on each side. So, 50% of 20 is 10. According to the theoretical probabilty, the coin would have landed on heads 10 times and tails 10 times. So, for that to be true Maria would have had to land on tails one more time.
