Math Problem Statement

Given the following information, answer questions a - d. P(A)=0.51 P(B)=0.55 A and B are independent. Round all answers to 5 decimal places as needed Find P(A∩B)

Solution

Given that events AA and BB are independent, the probability of both events happening (the intersection P(AB)P(A \cap B)) can be found using the formula for independent events:

P(AB)=P(A)×P(B)P(A \cap B) = P(A) \times P(B)

Given:

  • P(A)=0.51P(A) = 0.51
  • P(B)=0.55P(B) = 0.55

Now, compute P(AB)P(A \cap B):

P(AB)=0.51×0.55=0.2805P(A \cap B) = 0.51 \times 0.55 = 0.2805

Thus, the probability P(AB)P(A \cap B) is:

P(AB)=0.28050P(A \cap B) = 0.28050

Final answer:

P(AB)=0.28050P(A \cap B) = 0.28050

Here are 5 related questions:

  1. What is the probability of P(AB)P(A \cup B)?
  2. How does independence affect the calculation of P(AB)P(A \cap B)?
  3. If P(AB)=0.1P(A \cap B) = 0.1, what is the relationship between AA and BB?
  4. What happens if AA and BB are mutually exclusive instead of independent?
  5. How would P(AB)P(A \mid B) change if AA and BB were dependent?

Tip: Always verify whether events are independent or dependent before applying probability rules.
