Question:

At a local county fair, the officials would like to give a prize to 100 selected people at random from those attending the fair. As of the closing day, 12500 people have attended the fair and completed their entry form. The probability that an individual who attended the fair and completed the entry form will win a prize is:

Answer:


Probability = (1)/(125)

Explanation:

Given

Population = 12,500

Selection = 100

Required

Determine the probability that the selected person will win a prize

To do this, we simply divide the number of those that needs to be selected by the total population;

i.e.


Probability = (Selection)/(Population)


Probability = (100)/(12500)

Divide the numerator and denominator by 100


Probability = (1)/(125)

Hence, the required probability is ;


Probability = (1)/(125)
