Answer:
the answer for the equation 14
Amount doesn't come out even. She has 81 nickels but it doesn't account for 2 cents in the question.
15.9 units is the answer plus just for the future you should try plotting them down and adding that to the question.
Let x be a discrete binomial random variable that measures the number of successes in n trials.
Let p = 0.4 be the probability of success, that is, the probability that a deer has the aforementioned type of tick.
So the probability that 124 deer or less have this type of tick is calculated using the probability formula for a binomial distribution.
P (X <= x) = sum from x = 0 to x = 124 of (300! / ((X! * (300-x)!)) * (P ^ x) * (1-p) ^ n-x.
Finally the probability is 0.7030
