On each of the first three days of January, there is a 1/3 chance that it will snow where Bob lives. On each of the next four days, there is a 1/4 chance that it will snow. What is the probability that it snows at least once during the first week of January

Chance that is DOESN't snow 2/3 x 2/3 x 2/3 x 3/4 x 3/4 x 3/4 x 3/4 = 8/27 x 81/256 = 648/6912

1 - 648/6912 = 6264/6912 = 29/32 chance of snow (??)
