A bag contains 4 white, 3 blue, and 5 red marbles. Find the probability of choosing a blue marble, then a red marble if the marbles are not replaced.
A.5/44
B. 15/35
C. 2/5
D. 1/15

A.5/44

Step-by-step explanation:

marbles=12

The probability of choosing blue marble is 3/12=1/4.

Marbles are not replaced,

Then the total number is 11. The probability of choosing red is 5/11.

So the final answer is (1/4)*(5/11)=5/44.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
