Question

If A and B are two independent events such that

$P ( A ) = 0.40 , P ( B ) = 0.50$ Find $P$ (neither A nor B)

• A. 0.90
• B. 0.10
• C. 0.2
• D. 0.3

Answer 1

Answer: (D)

0.3

Answer 2

$P ($ neither $A$ nor $B ) = P ( \bar { A } \cap \bar { B } )$ P( u rks A o u B) $= P ( \bar { A } \cap \bar { B } )$

$= P ( \bar { A } ) \cdot P ( \bar { B } ) = 0.6 \times 0.5 = 0.30$.
