If P ( A )= 2 3 , P ( B )= 2 5 , and P ( A B )- P ( A B )= 2 5 , then what is P ( A B ) equal to?

Options

  1. A3 5
  2. B5 11
  3. C1 3
  4. DNone of the above

Correct answer

C. 1 3

Step-by-step solution

aligned & P ( A B )- P ( A B ) & = P ( A )+ P ( B )-2 P ( A B )= 2 5 & = 2 3 + 2 5 -2 P ( A B )= 2 5 & P ( A B )= 1 3 aligned
