Schritte zur Lösung

Find the probability of obtaining a total of 11:

\frac{1}{18}

Find the probability of 12:

0

Since the events are disjoint, Use the formula

P (X_{1} \lor X_{2} \lor \dots \lor X_{k}) = P (X_{1}) + P (X_{2}) + \dots + P (X_{k})

= \frac{1}{18} + 0

Apply rule:

a + 0 = a

= \frac{1}{18}
