Alice tossed a coin 100 times. In this experiment she recorded 53 heads and 47 tails. She

concluded that the probability of getting a head in a random toss is 53/100 = 0.53 and

getting a tail is 47/100 = 0.47.

Mark assumed that the coin is fair and so he concluded that the probabilities of getting a

head or a tail are the same, namely y2 = 0.5.

In determining the probabilities,

Alice used theoretical probability and Mark used empirical probability

A.

B. Both of them used theoreticall probability.

C. Both of them used empirical probability.

Alice used empirical probability and Mark used theoretical probability
