WebJan 5, 2024 · Since the probability that each student prefers math is independent of each other, we can simply multiply the individual probabilities together: P (all students do not prefer math) = .96 * .96 * .96 = .8847. This represents the probability that all three students do not prefer math as their favorite subject. 3. WebJun 22, 2024 · The probability of the intersection of two events is an important number because it is the probability that both events occur. Examples For our first example, suppose that we know the following values for probabilities: P (A B) = 0.8 and P ( B ) = 0.5. The probability P (A ∩ B) = 0.8 x 0.5 = 0.4. small claims montana https://anthonyneff.com
