I think the answer is 1/6
3n + 5p + 2 + n
Add up all the 'n's : 4n + 5p + 2
That's all you can do with it.
Answer:
you add it all up and lever the sides
Step-by-step explanation:
First, to find how many pints she drank, you divide 21 by 2, which is 10.5. To make things easier, let's convert her cups into decimal form by dividing 1 by 2, leaving us with .5.
Now, let's convert her pints to cups. 10.5 pints is equal to 21 cups. Now, add the cups she drank on the way home.
In total, Sasha drank 21.5 cups of water, or 172 fluid ounces :)
Answer:
85.29%
Step-by-step explanation:
We know 18 televisions sets contains 3 defective sets => 15 TV sets are ok
So the total number of possible ways for the hotel to buy = 
At least one of the defective sets, so we need to find the probability for 1 defective sets, 2 defective sets and 3 defective sets.
1. The number of ways the hotel purchases 8 of these televisions sets but have 1 defective one:
P(1) =
*
= 6435*3 = 19305
2. The number of ways the hotel purchases 8 of these televisions sets but have 2 defective one:
P(2) =
*
= 5005*3= 15015
3. The number of ways the hotel purchases 8 of these televisions sets but have 3 defective one:
P(3) =
*
= 3003*1 = 3003
So the probability that the hotel receives at least one of the defective sets =
(P(1) + P(2) + P(3) ) / P = (19305 +15015 + 3003 ) / 43785*100% = 85.29%
