Question

suppose the probability of success in a binomial event is 0.85. What is the probability of failure?
A. 0.95
B. 0.15
C. 0.05
D. 0.85

Answer 1

Answer:

Option B - 0.15

Step-by-step explanation:

Given : The probability of success in a binomial event is 0.85.

To find : What is the probability of failure?

Solution :

The probability of event is always 1.

i.e., sum of probability of success and failure is 1

The probability of success in a binomial event is P(S)=0.85.

$P(F)+P(S)=1$

$P(F)+0.85=1$

$P(F)=1-0.85$

$P(F)=0.15$

Therefore, Option B is correct.

The probability of failure is 0.15.
