1.) The numbers 1-12 are written on a card and placed in a bag. What is the probability that a number divisible by 3 is drawn? E
Pepsi [2]

<span>1.) In numbers from 1 to 12, there are  4 numbers that are divisible by 3 (3,6,9 and 12), meaning there will be 4 possible outcomes if a number will be drawn from 12 numbers. The probability of drawing a number divisible by 3 is 4/12 or 1/3.

2.) In the movie drawer, there are 15 movies,  seven are action movies, five comedies, and three dramas. The probability of choosing an action movie is 7/15, while a comedy is 5/15. The probability of choosing an action or a comedy is higher at (7/15+5/15) or 12/15 equivalent to 4/5.
3.) Having drawn 8 black marbles and 2 white marbles from a bag of 100 marbles give a probability of 8/10 (4/5) for black marbles and 2/10 (1/5) for white marbles. If there are 100 marbles, we can predict that there are 4/5(100) equivalent to 80 marbles in the bag.</span>

soldier1979 [14.2K]

Answer:

$56,900

Step-by-step explanation:

Given that:

Total sales in March = $151,000

Total variable cost = $94,100

The contribution margin for March can be obtained using the relation :

(Total sales - Total variable expenses)

($151,000 - $94,100)

= $56,900

Hence, contribution March for the month of March is $56,900
