Question

If P(blue) is 0.3, what is P(not blue)?\
A. 0.3
B. 0.5
C. 0.6
D. 0.7

Answer 1

Probability of Event Occurring + Probability of Event not occurring = 1.

Therefore:

P(blue) + P(not blue) = 1.

Therefore P(not blue) = 1 - P(blue)

P(blue) = 0.3

P(not blue) = 1 - P(blue) =1 -  0.3 = 0.7

P(not blue) = 0.7

Option D.
