The answer isn't always clear

Foe five days in a row the forecast was cloudy with 30% chance of rain. My grandson would ask me everyday will it rain today? He waited for the rain and on the fifth day he said when will it be our turn to be the 30% who get rain? I had no real answer for him no more than I do for those who are waiting for a chance to get ahead financially in this bad economy. When your chance for rain will come isn't always clear.
