First find the volume of the pool. To do so, multiply the length, times the width, times the height. In this case, it would be 12*15*5 and you get 900 cubic meters.
If the pool is being filled with 36 cubic meters of water per hour, you divide 900 by 36. You get 25 hours.
To check your work, multiply 25 hours and 36 cubic meters of water. You get 900 cubic meters, which is the area of the pool meaning it is full.

Amy rolls a number cube ten times and gets 3 four times! If she rolls the number cube 240 times, how many times should she get a
Iteru [2.4K]

Answer:

Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.

Step-by-step explanation:

Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.
