Explanation :
360/9=40 so I cookie has 40 calories

Recall that for a random variable
following a Bernoulli distribution
, we have the moment-generating function (MGF)
and also recall that the MGF of a sum of i.i.d. random variables is the product of the MGFs of each distribution:
So for a sum of Bernoulli-distributed i.i.d. random variables
, we have
which is the MGF of the binomial distribution
. (Indeed, the Bernoulli distribution is identical to the binomial distribution when
.)
