Two groups separately performed an experiment by tossing a coin in the air. Group A performed 50 trials and group B performed 100 trials. Each group recorded the results in the table below:

Group Heads Tails

A 30 20

B 52 48

What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails?

Maryjane Huerta · Answer 1

Theoretical probability;

Head = 1/2 or 50%

Tail = 1/2 or 50%

Group Heads Tails Total

A 30 20 50

B 52 48 100

Experimental probability:

Group A:

Heads : 30/50 = 60%

Tails: 20/50 = 40%

Group B:

Head: 52/100 = 52%

Tails: 48/100 = 48%

Experimental probabilities of Group B is closer to the theoretical probabilities.
