My brain isn't functioning right now...

 

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 it will snow in the first 3 days: 2/3

Chance that it will snow for the last four days: 3/4

 

(2/3)^3 times (3/4)^4 would get us the answer!

(Probability of snowing each of the three days)
(Probability of snowing each of the four days)

 

(2/3)^3 times (3/4)^4 = 3/32

1-3/32=29/32

 

So, our answer is 29/32
