The answer is .5 because to set it up you write 4.5/9 and then n/1 so 4.5 times 1 = 4.5 then you multiply 9 times n so it would be 9n, so then you didvide 9 by both sides so n=.5 so the unit rate is 1: .5

A local fraternity is conducting a raffle where 55 tickets are to be sold—one per customer. There are three prizes to be awarded

harkovskaia [24]

Answer:

(a) 0.0152%

(b) 1.1663%

(d) 79.3787%

Step-by-step explanation:

Tickets bought by organizers = 4

Number of tickets = 55

Prizes = 3

(a) The probability that the four organizers win all of the prizes is:

$P = \frac{4}{55}*\frac{3}{54}*\frac{2}{53}\\P=0.0152\%$

(b) The probability that the four organizers win exactly two of the prizes is:

$P = \frac{4}{55}*\frac{3}{54}*\frac{51}{53}+\frac{4}{55}*\frac{51}{54}*\frac{3}{53}+\frac{51}{55}*\frac{4}{54}*\frac{3}{53}\\P=1.1663\%$

(c) The probability that the four organizers win exactly one of the prizes is:

$P = \frac{4}{55}*\frac{51}{54}*\frac{50}{53}+\frac{51}{55}*\frac{4}{54}*\frac{50}{53}+\frac{51}{55}*\frac{50}{54}*\frac{4}{53}\\P=19.4397\%$

(d) The probability that the four organizers win none of the prizes is:

$P = \frac{51}{55}*\frac{50}{54}*\frac{49}{53}}\\P=79.3787\%$
