In the game of Monopoly, a player is sent to jail if he or she rolls doubles with a pair of dice 3 times in a row.What is the probability of rolling doubles on a single turn? (Enter your probability as a fraction.) _______What is the probability of rolling doubles 3 times in succession? (Enter your probability as a fraction.) _______

Sagot :

The probability of rolling doubles on a single turn is the number of favorable cases over the number of total cases, the favorable cases are those when you get a double, the number of total cases is the number of total possible outcomes.

Now, the number of total possible outcomes is

[tex]6\times6=36.[/tex]

The number of favorable cases is

[tex]6.[/tex]

Therefore, the probability of rolling doubles is:

[tex]\frac{6}{36}=\frac{1}{6}\text{.}[/tex]

Now, the probability of rolling double 3 times in succession is the product of rolling a double in a single turn, therefore:

[tex]P=\frac{1}{6}\times\frac{1}{6}\times\frac{1}{6}=\frac{1}{216}.[/tex]

Answer:

The probability of rolling doubles on a single turn is:

[tex]\frac{1}{6}\text{.}[/tex]

The probability of rolling doubles 3 times in succession is:

[tex]\frac{1}{216}\text{.}[/tex]
