Answer:
0.3960
Step-by-step explanation:
X - no of questions answered correct is binomial since each question is independent of the other and there are two outcomes
p = Prob of any one question right = 0.2  (1/5)
n = 44
Normal approximation would be mean = np = 8.8 and Variance = npq = 7.04
Std dev = 
X is N(8.8,2.6534)
Or Z = 
Since we approximate discrete to continuous continuity correction is to be applied
 means x≥9.5
 means x≥9.5
P(X≥9.5) = 0.3960
