Adiscount store takes 50% off of the retail price of a desk. for the store's holiday sale, it takes an additional 20% off of all furniture. the desk's retail price was $320. how much is the desk on sale for during the holiday sale?  

store gives 50% and additional 20 % offer on furniture

50 % is for desk and additional 20% is for furniture we know dest belongs to furniture category.

so total discount is 70 %

we know that cost price of desk $320 dollar

so after the discount value cost will be =

we will have discount of 224 from 320

so sale price will be =320 -224=$96.

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
