Answer from: sakinahunt

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:

The experimental probability is closer to the theoretical probability for group Q than group P. Step-by-step explanation:

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%

The experimental probability is closer to the theoretical probability for group Q than group P.

D. The experimental probability is closer to the theoretical probability for group H than group G.
With any experimental probability, the more trials that are done will make the experiment move more likely to be the theoretical probability. in this case, the theoretical probability for flipping a coin is 50 heads 50 tails which H is closer to. any statistical data the more data collected the more close to reality it is.

Answer from: harkey
H/(H+T) in theoretical probability is of course 1/2 or 0.5

Group E had an experimental probability of 32/50 or 0.64

Group F had an experimental probability of 52/100 or 0.52

So the experimental probability is closer to the theoretical probability for group F than group E.

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

The experimental probability is closer to the theoretical probability for group Q than group P.

Step-by-step explanation:

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:

Group Heads Tail

 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,

Group Heads Tail

  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%

The experimental probability is closer to the theoretical probability for group Q than group P.

hope this helped bro
