Let E_1, E₂, E₃ and E₄ be events with the following probabilities: P(E₁) = 1/4, P(E₂) = 2/5, P(E₃) = 1/6, P(E₄) = 1/5.

E₁ and E₂ are mutually exclusive events, while E₃ and E₄ are independent events.

Let,

A = probability of neither E₁ nor E₂ occurring

B = probability of exactly one of E₃ or E₄ occurring.

What are the values of A and B?

• A.

  A = 0.35, B = 0.150

• B.

  A = 0.15, B = 0.148

• C.

  A = 0.10, B = 0.300

• D.

  A = 0.35, B = 0.300
