Admin How many ways can you pick 3 out of 5?
10 possible combinations
So 5 choose 3 = 10 possible combinations.
How do you find the probability of combinations?
To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time. To find the probability of an event, you may have to find the combinations.
How many ways can you pick 3 out of 6?
= 15 ways. You divide by 3! to eliminate order.

What is the probability of an event happening?
Probability of an event happening = Number of ways it can happen Total number of outcomes Example: the chances of rolling a “4” with a die Number of ways it can happen: 1 (there is only 1 face with a “4” on it) Total number of outcomes: 6 (there are 6 faces altogether)
What is the probability of a single die being thrown?
