The probability of an event occurring is the number of favorable cases divided by the number of possible cases. If the probability is equal to 0 then the event is impossible. If the probability is equal to 1 then the event is certain.

In a urn balls of identical balls numbered from 1 to 30 a ball is extracted. Calculate the probability that the extracted ball is a multiple of 5.

Number of favorable cases

{2, 4, 6, 8, 10}

p = 5 / 10

p = 0.5 = 50%
