c.)
When a coin is tossed, there is a probability of 1/2 getting a tail.
The word INDIANAPOLIS has 12 letters in total, with 2 Ns. This gives us a probability of 2/12.
Therefore:
[tex]P\left(tails,thenN\right)=\frac{1}{2}\times\frac{2}{12}=\frac{1}{12}[/tex]d.) P(heads, then D or I)
When a coin is tossed, there is a probability of 1/2 getting a heads).
There would be a probability of 5/12 when getting a D or an I.
Therefore:
[tex]P=\frac{1}{2}\times\frac{5}{12}=\frac{5}{24}[/tex]
