Math Problem Statement

Let A, B, and C be independent events with P(A) = 0.1, P(B) = 0.6, and P(C) = 0.9. Find P(A ∩ B ∩ C).

Solution

The problem you're working on involves finding the probability P(ABC)P(A \cap B \cap C), where AA, BB, and CC are independent events, given:

  • P(A)=0.1P(A) = 0.1
  • P(B)=0.6P(B) = 0.6
  • P(C)=0.9P(C) = 0.9

Since AA, BB, and CC are independent events, the probability of all three occurring simultaneously (the intersection P(ABC)P(A \cap B \cap C)) is simply the product of the individual probabilities:

P(ABC)=P(A)×P(B)×P(C)P(A \cap B \cap C) = P(A) \times P(B) \times P(C)

Now, let's calculate this.

P(ABC)=0.1×0.6×0.9P(A \cap B \cap C) = 0.1 \times 0.6 \times 0.9

I'll compute this for you.The probability of AA, BB, and CC all occurring together, P(ABC)P(A \cap B \cap C), is 0.0540.054.

Would you like a detailed explanation of this process, or do you have any further questions?

  1. How do you find the probability of the union of independent events?
  2. What happens if events AA, BB, and CC are not independent?
  3. Can you explain the difference between independent and mutually exclusive events?
  4. How do you calculate the conditional probability P(AB)P(A \mid B)?
  5. What is the formula for calculating P(AB)P(A \cup B)?

Tip: When events are independent, their joint probability is simply the product of their individual probabilities.
