The probability that least one of the events E₁ and occurs is 0.6. If the simultaneous occurrence of E₁ and E₂ is 0.2 , P ( E ₁ ^ )+ P ( E ₂^ )=

Options

  1. A0.4
  2. B1.6
  3. C1.2
  4. D0.8

Correct answer

C. 1.2

Step-by-step solution

aligned & P (E₁ E₂ )=P (E₁ )+P (E₂ )-P (E₁ E₂ ) & 0.6= [1-P (E₁ ^ )+1-P (E₂ ^ )-P (E₁ E₂ ) ] & P (E₁ ^ )+P (E₂ ^ )=2-0.2-0.6=1.2 aligned
