\u201cMommy, I want my cereal, my Munchy Crunchies,\u201d pleaded Junior at the breakfast table. Mommy placed the cereal box, almond milk and honey in front of Junior.<\/p>\n
While munching away Junior was avidly reading the promotional text on the back of the cereal box.<\/p>\n
\u201cMommy, it says here that if I collect five famous Disney character cards, I will get a prize \u2013 a scout compass. There is one card in each box. Let\u2019s quickly buy five boxes of Munchy Crunchies so I can get the compass for my Boy Scout trips,\u201d suggested Junior with a bright enthusiastic look.<\/p>\n
Daddy overheard Junior. \u201cIt doesn\u2019t quite work that way, son. Maybe the five boxes we buy all have the same character card, or maybe just one different card.\u201d<\/p>\n
Junior was not discouraged. \u201cIt also says that cards have one of five colors on the other side: red, blue, green, yellow and orange,\u201d informed Junior. \u201cIf all of the five character cards have a red back side, I can also win a Speedo bicycle. Please, daddy, we have to buy more boxes today,\u201d pleaded Junior, munching away faster.<\/p>\n
\u201cHmm,\u201d said daddy.<\/p>\n
\u201cAnd, daddy, it also says that in one of every thousand boxes there is a gift card for a free trip to Disneyland for a family of three, with all expenses paid,\u201d said Junior beaming.<\/p>\n
Daddy became more interested. \u201cHmm, I will work out our chances for all this,\u201d he said prudently, grabbed his calculator and went to his work room.<\/p>\n
\u201cThanks, dad.\u201d Junior was beaming with pleasure, thinking of the great prizes he would win and how much he would enjoy going to Disneyland.<\/p>\n
Mommy cleaned the table. Then she made two cups of coffee and went to talk with daddy.<\/p>\n
