If P(blue) is 0.3, what is P(not blue)?
A. 0.3
B. 0.5
C. 0.6
D. 0.7
P(not blue) = 1 - P(blue) = 1 - 0.3 = 0.7
Therefore, the answer is D. 0.7.
To find the probability of the complement event (not blue), subtract the probability of the event (blue) from 1.
P(not blue) = 1 - P(blue) = 1 - 0.3 = 0.7
Therefore, the correct answer is D. 0.7
