The correct response for #32 is listed at the bottom of this posting. Did you obtain that? Make sure you double-check your work, as this is a good number sense type question for our current unit.
First, I found out how many of each card was there... 500/5=100 $5 cards 500/10=50 $10 cards 500/20=25 $20 cards 500/50=10 $50 cards 500/100=5 $100 cards Therefore, there are 5+10+25+50+100=190 total possible outcomes. However, the question is asking for the chances to win more than 15$. The only 3 types of cars that will fit in this category are $20, $50, and $100 cards. There are 5+10+25=40 possibilities. At the end, the probability is 40/190 which reduces to 4/19 that you will win more than you paid for to participate in this game.
