Final answer:
The multiplication rule of probability states that if two events A and B are independent, then the probability of both events occurring together of both A and B happening is 0.6 * 0.4 = 0.24.
Step-by-step explanation:
The multiplication rule of probability, also known as the multiplication rule of independent events, states that if two events A and B are independent, then the probability of both events occurring together is equal to the product of their individual probabilities. Mathematically, this can be represented as:
P(A AND B) = P(A) * P(B)
For example, if the probability of event A happening is 0.6 and the probability of event B happening is 0.4, then the probability of both A and B happening is 0.6 * 0.4 = 0.24.
