You roll a fair number cube twice. Find P(3, then 5)

yes

Step-by-step explanation:

With one die the P(3) = P(5) = 1 /6. For 2 dice there are 2 ways to roll a 3 and 4 ways to roll a 5. 7 ways to roll a 3 or 5 so P(3 or 5) = 6/36 or 1/6

1/36

Step-by-step explanation:

the probability of getting 3 the first time is 1/6

the probability of getting 5 the second time is 1/6

1/6•1/6=

1•1=1

6•6=36

1/36

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:

practice. practice. practice.
