Question

Can anyone tell me the answer and calculations for #2

Answer 1

If t the possibilities  the  to win are 1/16,.then the possibilities   to lose are 15/16

16/16-1/16=15/16

so  every 15 of the  16  times they will raise 25 cents which is almost 100% of the times

 Every15 of 16 times they will raise $15.But also they need to give away$5 price

so $10 every 15/16
