Suppose we have two unfair coins. The probability of getting head from each of them is 0.75. If we flip those two unfair coins, we write down the probability distribution for the number of heads. a. Find the expected value.
b. Calculate the variance.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

can you complete your sentence? i could !

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
