Question 1115896

Assuming independence, 0.02*0.02=0.0004
On time next two days is 0.79^2, the 0.79 being 1.00-0.19-0.02
=0.6241

The first is the stated probability squared.
The second requires using the complement to get the required probability and then squaring it. 
Note: sometimes, people refer to on time as early as well.  It isn't clear from this question that is the case.  If coming early is "on time" then the answer to the last is 0.81^2 or 0.6561.
