Two groups performed an experiment separately by tossing a coin in the air. Group P performed 50 trials and group Q performed 100 trials. Each group recorded the results in the table below: Group Heads Tails P 35 15 Q 53 47 What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails? The experimental probability and the theoretical probability for group P is the same. The experimental probability and the theoretical probability for group Q is the same.The experimental probability is closer to the theoretical probability for group Q than group P.The experimental probability is closer to the theoretical probability for group P than group Q.

100
Experimental
probability:
Group P:
Heads : 35/50 = 70%
Tails: 15/50 = 30%
Group Q:
Head: 53/100 = 53%
Tails: 47/100 = 47%
