12345 [234]

Answer:

probability that exactly 4 out of 9 questions are correct is 0.111

Step-by-step explanation:

Given data:

Test consist of multiple choice question which as 4 choices

Total number of answer randomly = 9

Probability of having 4 answer correctly is calculated as

p = probability of having particular question is answered in correct way

= 1/4 = 0.25

q = probability of having particular question is answered incorrectly

= 3/4 = 0.75

Binomial expansion is beneficial in various situations at which numerical variables are present that are countable or whole numbers

probability that exactly 4 out of 9 questions are correct

$= ^9C_4 (0.25)^4 (0.75)^5$

$= 120\ times 0.00390 \times 0.2373$

= 0.111
