When two events A and B are mutually exclusive (disjoint), such as a student earning an "A" or earning a "B" on a test, the probability of the union of the two events is equal to their individual probabilities.

the sum of

Step-by-step explanation:

The probability of the union of two events is equal to the sum of individual probabilities. The union of two set contains all the elements of previous sets. The union is denoted by ∪. The equation for the students earnings will be expressed as P(A∪B). The occurrence of event A changes the probability of B then the events are dependent. If the probability of two events happening together is zero then the events are mutually exclusive.

i would need to see the dot plot : )
