We roll a fair 6-sided die 5 times. what is the probability that we get an odd number in exactly 4 of the 5 rolls

Step-by-step explanation:

The die is 6-sided. This means that there are 3 odd numbers and 3 even numbers.

When the die is rolled once, the probability of getting an odd number is:

3/6 = 1/2

The probability that this event will occur 4 out of 5 times will be:

4/5 * 1/2 = 4/10 = 2/5

step-by-step explanation:

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:
