Currently the bus runs every 7 minutes during the day. Let X represent the amount of time Sofia waits for the bus, assuming she arrives at the bus stop at a random time and the bus is running on schedule. (That is, the amount of time Sofia waits is uniformly distributed.) Find the following probabilities (use 2 decimal places for all answers):

(a) The probability Sofia waits at most 2 minute(s) =

(b) The probability Sofia waits less than 2 minute(s) =  

(c) The probability Sofia waits between 2 and 4 minutes =  

(d) The probability Sofia waits less than 2 minute(s) or more than 4 minutes =
