Question

If a coin is tossed 75 times and it lands on head 36 times what is the experimental probability of it landing on tails and what is the theoretical probability of it landing on tails

Answer 1

Explanation:

Exper. prob. of landing on tails: (75-36) / 75 = 39/75 = 0.52

Theoretical probability, which assumes that the coin is "fair:" (75/2)/75 = 0.50

Answer 2

Experimental : 39/75

Theoretical : 37.5/75

Explanation:

If it lands on heads 36 times and has been tossed a total of 75 times, we subtract 36 from 75 to find the number of times it landed on tails and the experimental probability.

75 - 36 = 39

39/75 is the experimental probability

There are only 2 outcomes when tossing a coin, heads and tails.

So the theoretical probability is 75 / 2.

75/2 = 37.5

37.5/75 is the theoretical probability.
