Question

Probability question. Geometry please look in comments for question!

Answer 1

Hint: (THIS IS AN EXAMPLE, not solution to the above problem)
If you throw a die, the probability of NOT throwing a two is
1-P(2)=1-(1/6)=5/6
OR
you add up the probabilities of everything else:
P(not a 2)=P(1)+P(3)+P(4)+P(5)+P(6)=5/6.
