Answer:
0.00259
Step-by-step explanation:
Probability, p of making the correct guess ; 1 / 5 = 0.2
Passing grade = 50% ; 50% * 20 = 0.5 * 20 = 10
q = probability of not passing ;
q = 1 - p = 1 - 0.2 = 0.8
Using the binomial distribution formula :
P(x >=x) = nCx * p^x * (1 - p)^(n - x)
P(x >= 10) = p(x = 10) + p(x = 11)+... + p(x = 20)
P(x >= 10) = 10C20 * 0.2^10 * 0.8^10
P(x >=) 0.00259
