What is the sample space in probability?

Back

The sample space is the set of all possible outcomes of a probability experiment. For example, the sample space for flipping a coin is {Heads, Tails}.

How do you express probability as a fraction?

Back

Probability is expressed as a fraction of the number of favorable outcomes to the total number of possible outcomes. For example, if there are 3 favorable outcomes out of 10 possible outcomes, the probability is expressed as 3/10.
