Question: Rosanne runs a stable that boards 20 horses, and 8 of them are spotted. What is the experimental probability that the next horse that comes to board will be spotted?
Write your answer as a fraction or whole number.
(1) 2/4
(2) 2/5
(3) 2/1
(4) 2/6
Solution:
REMEMBER : The experimental probability is the number of times an event occurs out of the total number of trials.
Write the experimental probability as a fraction in simplest form.
P(spotted) = spotted/total
= 8/20
= 2/5
So, P(spotted) = 2/5
Then the option is (2) 2/5.
