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.

Theoretical probability;

Head = 1/2 or 50%

Tail = 1/2 or 50%

Group     Heads      Tails      Total

A                35          15          50

B                53          47        100

Experimental probability:

Group P: 

Heads : 35/50 = 70%

Tails: 15/50 = 30%

Group Q:

Head: 53/100 = 53%

Tails: 47/100 = 47%

The experimental probability and the theoretical probability for group Q is the same

The conclusion that can be drawn about the number of trials and probability of the coin landing on heads or tails is:

We know that the theoretical probability for choosing a coin on heads or tails is:

            1/2=50%

( Since, there are only two possibilities on tossing a coin either head or tail comes up)

Now, for group P the experimental frequency is:

GroupHeadsTail

  P             35  15

Hence, Probability(getting head)=35/50=0.7

in percent it is: 70%

and the Probability(getting tail)=15/50=0.3

in percent it is: 30%

Similarly,

GroupHeadsTail

   Q            53          47

Hence, Probability(getting head)=53/100=0.53

in percent it is: 53%

and the Probability(getting tail)=47/100=0.47

in percent it is: 47%
