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?

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.
