Question

Liz flips a coin 90 times. The coin lands head up 63 times and tails up 27 times. The theoretical probability of the coin landing heads up is ___​%.

Answer 1

Answer:

50%

Step-by-step explanation:

This question asks for the theoretical probability

In order to find theoretical probability, we find how many outcomes are possible, and how likely each action is.

In this case, we are flipping a coin. There are only two possible outcomes of this, which are heads and tails. Each of these are equally likely, so that would mean the theoretical probability of flipping it and it landing heads up is 50%

Answer 2

Answer:

P(head up) = 70%

Explanation:

P(head up) = 63/90

P(head up) = 7/10

P(head up) = 70%
