Given that is a sample space of a random experiment, where
, and , determine .
The notation refers to the probability of either event or event occurring.
Since and are two different elements, then . First, use this fact to determine the probability of as follows:
Since and are two different elements, then . Now use this fact to determine the probability of .
Since , , , and are different elements, and they make up the sample space, the sum of their probabilities must be equal to 1.
Next, use this fact to find the probability of .
Thus, the probability of is 0.37.
