 Smokey's Smokes (Posted on 2010-06-03)
A store sells three brands of cigarettes: \$3.15 Star lights, \$4.30 Vegas slims, and \$5.20 Royal 100's. (Tax included) A man named Smokey walks into the store, and buys 2 packs of cigarettes, one pack for himself and the other pack for a friend. He hands the cashier a \$20 note, and is returned a few bills and 3 coins in change (exclude dollars or half dollars). What's the probability, that the man smokes Royal 100's?

Ans:  ZERO  PROBABILITY

solution :

3.15+5.2=8.35   20-8.35=11.65  no way  in 3coins

4.3+5.2=9.5     20-9.5=10.5  no way  in 3coins

3.15+4.3=7.45 change  20-7.45=12.55      ok in 3coins:   25+25+5=55  - without  Royal
