Acoin is flipped 20 times. the results are 12 heads and 8 tails. the theoretical probability of getting heads is 60% true or false

FALSE

Step-by-step explanation:

What we have here is experimental probability:   12 heads out of 20 tosses.

The fraction 12/20 reduces to  6/10, or 0.60, which corresponds to 60%.

The answer to this question is FALSE, because this is not theoretical probability.

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9
