Step-by-step explanation:
Given that a math exam has 44 multiple choice questions, each with choices a to d.
A student answers just by guessing. So no of questions he answers X is binomial with constant probability 1/4 = 0.25
We can find probabibility using binomial as
P(X=12) =
If approximated to normal we have
mean = np = 11
Std dev =
With continuity correction we get
P(X<12)
=P(X<11.5)
=0.5691
