During the second day of the school fair, Talia and Yoshi recorded 43 winners out of a total of 324 players. How does the actual number of winners compare to the expected number of winners?

Theorical probability

P (red) = 1/8 = 12.5%

Experimental probability

(?) / 324 = (?) %

This experimental probability is (?) than the theoretical probability.

There were (?) winners than expected.

    The experimental probability is 0.8% more than the theretical probability,

    There were approximately 2 more winners than expected

    Step-by-step explanation:

    Theoretical Probability is given by = 1/8 = 12.5%

    Which means that out of 324 players, numbers of winners theoretically are = 0.125 · 324 = 40.5 ≅ 41

    To find the probability of experimental data, we have to consider the data recorded by Talia and Yoshi

    Recorded winners = 43

    Total players = 324

    Experimental Probability = Numbers of winners / Total Number of players · 100

    Experimental Probability = 43/321 · 100 = 13.3%

    The difference between Experimental and Theoretical Probability is = 13.3% - 12.5% = 0.8%

    Difference of Winners ≅ 43 - 40.5 ≅ 2
