The answer is 6/13 since there are 12 distinct letters in the phrase and 12/26 is written as 6/13
The probability that Luca will win Wheel of Letters for this considered case is 6/13
How to calculate the probability of an event?
Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, the sample space of result of wheel of letters spin is
S = {A, B, ..., Z} , thus, n(S) = size of S = 26
Let E = event that the spinner will stop in one of the letters in “COUNTRY PHRASE”
Then, the outcomes in favor of E are {'P', 'O', 'C', 'A', 'T', 'R', 'Y', 'N', 'H', 'S', 'U', 'E'}
Thus, n(Favorable cases for E) = 12 (counted unique ones, and not repeated), as each letter is only 1 time in the spinner.
Thus, we get:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{12}{26} =\dfrac{6}{13}[/tex]
Thus, the probability that Luca will win Wheel of Letters for this considered case is 6/13
