Question

If P(A)=0.3, then the probability of the complement of A is ?
A. 0.5
B. -0.3
C. 0.3
D. 0.7

Answer 1

C is the answer for this question

Answer 2

The probability of the complement of A is 0.7.

We know that the complement formula is: P(A') = 1 - P(A).

Using the formula we get:

P(A') = 1 - P(A)

P(A') = 1 - 0.3

P(A') = 0.7
