So 119 out of 250 people had a pool in their backyard...119/250 = 47.6%

so out of 10,000 people, expected value of ones with a pool is :
47.6% of 10,000 ...
0.476 * 10,000 = 4760 people <===

Find the probalitywhen a pair of 8-sided fair die is rolled and the sum of the roll is greater than 9
Tresset [83]

Odd Numbers : 1, 3, 5, 7 = 4 numbers

Total numbers on 8-sided die = 8

P(rolling an odd number) = 4/8 = 1/2

Die is defined as ceasing to live, exist, or disappear. An example of this is pulling a plant out of the ground by its roots. An example of death is when a person's heart stops and the brain stops working. stop living; dead out.

Use ``die of'' when someone dies of direct causes. We use ``die of'' when someone died from an indirect cause. "die by" is used when someone dies from something. He died of cancer.

A person drinks 1 pint of milk a day. At this rate how many gallons will a person drink in a leap year (366 days)?
Diano4ka-milaya [45]
OK. SO first you need to know how many pints are in a gallon.  ( one gallon = 8 quarts ) 

One day = one pint. So we want to find what 366 days equals. 1*366=366 pints in 366 days. We now have 366 pints. We need to convert that to gallons. One gallon equals 8 quarts, so we divide 366 by 8. 366/8= 45.75

So in one leap year a person drinks 45.75 gallons of milk

If that doesn't make sense, ask and i can re explain. Hope that helped! <span />
