Monthly Earnings (X) = Monthly Revenue (P*Q) – Monthly Expense (F+V+L) =P*Q – (3995+L+11*Q) There are three variables in this equation‚ with the assumption; this model is realistic enough‚ if I was Sanjay‚ I will consider what the shape of the probability distribution of X is‚ and the measurement of this distribution to make risk analysis. a). Without considering the partnership opportunity‚ to solve the case‚ we run a Crystal Ball simulation with 1000 trials. The assumption variables are P‚ Q‚

What is the probability that at least two students were born on the same day of the year? For simplify the math‚ without changing the result significantly‚ let’s assume that year is always 365 days long (no February 29 birthdays) and let’s assume that a person has an equal chance of being born on any day of the year‚ although some birthday may be slightly more likely than others. If the students are 366 the probability would be equal to 1. If there is just 1 student the probability would be

If A and B are two events‚ then the conditional probability A given B is written as P ( A | B ) and read as “the probability of A given that B has already occurred.” We are to calculate the probability of the intersection of the events F and G. P(F and G) = P(F) P(G |F) P(F) = 13/40 P(G |F)
