Question

ent a or b: the selected ball is white or has an even number on... ent a and b: the selected ball is white and has an even number on... ) compute the following. p(a) + p(b) − p(a and b) : dropdown options: p(a or b), p(a and b), p(b), p(a) (c) select the answer that makes the p(a) + p(b) − p(a and b) = select

Explanation:

The formula \( P(A) + P(B) - P(A \text{ and } B) \) is the addition rule for probability, which calculates the probability of event \( A \) or event \( B \) occurring (i.e., \( P(A \text{ or } B) \)). This is a fundamental concept in probability theory (a subfield of Statistics in Mathematics) where the probability of the union of two events is found by adding the probabilities of each event and subtracting the probability of their intersection to avoid double - counting.

Answer:

\( P(A) + P(B) - P(A \text{ and } B)=P(A \text{ or } B) \)
