<em>Question:</em>
<em>Which of the following is NOT a formula for determining complementary probability?</em>
<em>A. P(outcome) = 1- P(-outcome)</em>
<em>B. P(outcome) - P(-outcome) = 1</em>
<em>C. P(outcome) + P(-outcome) =1</em>
<em>D. P(-outcome) = 1 - P(outcome)</em>
<em></em>
Answer:
Step-by-step explanation:
Required
Determine which option is not a formula of complementary probabilities
From the list of given options, the complementary probabilities are P(outcome) and P(-outcome)
In probability;
--- Equation 1
Subtract P(outcome) from both sides
------ Equation 2
Subtract P(-outcome) from both sides of equation 1
Equation 1, 2 and 3 represents options A, C and D
While option B is out of place
<em>Hence, option B is not a formula of complementary probability</em>
