The elevations in relation to sea level, 0 feet, of some locations in the United States are shown in the table. Which expression can be used to find the distance between the elevations of Mount Washington and New Orleans?

–7 – (–6,288)
6,288 – 7
–7 – 6,288
6,288−(−7)

the correct answer is the second option

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
