The Venn diagram below shows a sample space, S, of equally likely outcomes and events A and B. Find the following probabilities.

 

 

a. The probability of A:  P(A)

b. The probability of B:  P(B)

c. The probability of A 'given' B: P(A|B)

d. The probability of B 'given' A: P(B|A)

This image depicts a Venn diagram illustrating the relationship between two sets, \(A\) and \(B\), within a universal set \(S\).

- **Sets \(A\) and \(B\):** These are represented as two intersecting circles within a rectangular boundary, which symbolizes the universal set \(S\).
- **Universal Set \(S\):** The rectangle surrounding the two circles, indicating the entire universe of possible elements for this context.
- **Elements:**
  - The elements are shown as small blue dots.
  - Some dots are located inside circle \(A\) but outside circle \(B\), representing elements unique to set \(A\).
  - Some dots are inside circle \(B\) but outside circle \(A\), indicating elements unique to set \(B\).
  - The overlapping region of the circles contains dots that are common to both sets \(A\) and \(B\), representing the intersection of the two sets.
  - There are also dots outside both circles, but within the rectangle, indicating elements that are in the universal set but not in either set \(A\) or \(B\).

This diagram helps in understanding concepts like union, intersection, and difference of sets.
