Question

If E and F be mutually exclusive events in a sample space such that P(5) = 0.3 and P(F) = 0.6, then P( $\overline { \mathrm { E } }$ Ē $\overline { \mathrm { F } }$ ) equals–

• A. 0.3
• B. 0.9
• C. 0.1
• D. 0.7

Answer 1

Answer: (C)

0.1

Answer 2

P ( $\overline { \mathrm { E } }$ Ē ) = P [(E Č F)C] = 1 – P(E Č F)

= 1 – {P (5) + P(F)} = 0.1
