Calculating probability Determine a single event with a single outcome. The first step to solving a probability problem is determining the probability you want to calculate. ... Identify the total number of outcomes that can occur. ... Divide the number of events by the number of possible outcomes.

The more likely something is to happen, the higher its probability. We think about probabilities all the time. For example, you may have seen that there is a 20% chance of rain on a certain day or thought about how likely you are to roll a 6 when playing a game, or to win in a raffle when you buy a ticket.

Practice Questions Write the sample space for rolling two dice. If two coins are tossed simultaneously, what is the probability of getting exactly two heads? From a well-shuffled deck of 52 cards, what is the probability of getting a king? In a bag, there are 5 red balls and 7 black balls.

For example, if you throw a die, then the probability of getting 1 is 1/6. Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6.
