alleryIf P(A) = 0.4, the probability of complement of A is
Aexactly zero
Bexactly zero point four
Cexactly zero point six
Dexactly one point six
Answer & Solution
Correct answer: C. exactly zero point six
1. The complement rule: P(A) + P(not A) = 1.
2. P(not A) = 1 - P(A) = 1 - 0.4.
3. = 0.6.
4. So P(complement of A) equals 0.6, written as 'exactly zero point six'.
