A bag contains 3 white marbles and 6 black marbles. You pick out a marble, record its color, and put the marble back in the bag.
VARVARA [1.3K]
24 times you'd theoretically draw a black marble.
There is 9 marbles in the bag. Out of the 9, 6 are black so you have a \frac{6}{9} chance to draw a black marble. \frac{6}{9} multiplied my 36 is 24.(For this short cut, you multiply the favorable event's probability by the number of trials.)

Yesenia buys water to make tea for all her friends. She buys 1 qurt of water and 1/2 gallon of water. How many cups of water doe
Lina20 [59]

Answer:

12 cups of water

Step-by-step explanation:

This question has to do with conversion

We are told that she buy 1 quart and 1/2 gallon of water.

Hence,

1 quart of water = 4 cups of water

1 gallon of water = 16 cups of water

1/2 gallon of water = x

Cross Multiple

x = 1/2 × 16 cups of water

x = 8 cups of water.

Therefore, the total cups of water that she bought = 4 cups of water + 8 cups of water = 12 cups of water
