So basically, these numbers have to be consecutive because they're facing pages.
So you can just divide this by 2, and then add one to the second number.
629/2 = 314 R1
So the first page number is 314, and for the second one, just add one, and you get 315.

Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

The probability of finding a value higher than x is:

The average lifetime of a certain new cell phone is 3.4 years.
This means that 
So

68% of these phones last how long (in years)?
This is x for which:


Then






68% of these phones last 3.87 years.
