P(4)=1%2F6
P(less than 6)=5%2F6
P(4 or less than 6)=1/6+5/6-1/6=5%2F6
We have to subtract 1/6 so as not to double count 4, since 4 is also count as a sum less than 6.

A standard number cube (#1-6 on six sides) is tossed. Find each probability.
-----------------
P(4 or less than 6) = P(4)+P(less than 6) - P(4 and less than 6)
---
= (1/6) + (5/6) - (1/6)
===
= (5/6)
