Dividing the number of events by the number of possible events is very simplistic, and it isn’t suited to finding probabilities for a lot of situations. Tech and Engineering - Questions & Answers, Health and Medicine - Questions & Answers, Economists often distinguish between the terms risk and uncertainty- risks arise when we can enumerate all of the possible outcomes of a future event, but we don't know the outcome yet. However, subjective probability does not base its pro… Group 1 2 3 4 5 6 Age (in years) Under 5 5-19 20-24 25-44 45-64 65 and over Number (in thousands) 21,265 61,376 21,225 8. For example, the probability of picking up an ace in a 52 deck of cards is 4/52; since there are 4 aces in the deck. The typical example of classical probability would be a fair dice roll because it is equally probable that you will land on any of the 6 numbers on the die: 1, 2, 3, 4, 5, or 6. Or, you can divide the number of favorable outcomes by the total number of possible outcomes and state the probability as a percentage.
