Suppose the number of children in a household has a binomial distribution with parameters n=23 n
=
23
and p=35
p
=
35
%.

Find the probability of a household having:

(a) 8 or 15 children
(b) 13 or fewer children
(c) 21 or more children
(d) fewer than 15 children
(e) more than 13 children

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

$250 deductible means jane must pay the first $250 of her bill. so the insurance company paid = (80% of bill) - deductible = (0.8 x $2550) - $250 = $2040 - $250 = $1790 and jane's cost is = (bill) - (insurance payment) = $2550 - $1790 = $760
