Mathematics

normal approximation not appropriate in this instance because

np = 3300 * 0.9998 = 3299.3 5

and

nq = 3300 * 0.0002 = 0.66 < 5

The probability is P(X = 3300) = 0.52

The probability is P(X = 3287) = 0

Step-by-step explanation:

From the question we are told that

The sample size is n = 3300

The chance of liking blueberry pie is p = 0.9998

The chance of not liking blueberry pie is q = 0.0002

For normal approximation is possible if

np 5 , nq 5

Now let test

np = 3300 * 0.9998 = 3299.3 5

and

nq = 3300 * 0.0002 = 0.66 < 5

The probability that all 3300 people will say they like blueberry pie is mathematically represented as

$P(X = 3300) = p^{3300}$

$P(X = 3300) = (0.9998)^{3300}$

P(X = 3300) = 0.52

The probability that 3297 of the people will say that they like blueberry pie is mathematically represented as

$P(X = 3287) = \frac{(np)^{3297! } * e^{-np}}{3297}$

$P(X = 3287) = \frac{0}{\infty}$

P(X = 3287) = 0
