Question

The probability I pass a test is 0.8, what is the probability I fail?

Answer 1

Answer:

P(pass) +p(fail) =1

So if p(pass) =. 8 therefore

P(fail) =1-0.8=.2

Answer 2

Hello!

Here is the answer for your question!

Question:- The probability I pass a test is 0.8, what is the probability I fail?

------------------------------------------------------------------

Answer:-

• The total sum of probabilities of all outcomes is equal to 1
• Here only two outcomes are possible either passing the test or failing the test

So, The probability of failing the test = 1 - 0.8 = 0.2

• The probability of failing the test is 0.2
