Answer:
Step-by-step explanation:
Given: A three-character code uses the letters C and P.
If repetition is allowed then the total number of ways to make the three letter character code using two letters C and P is given by :-
Since the PCP is one of the character code, therefore , the probability of the code PCP is given by :-
Hence, the probability of the code PCP =
1/8
When there are two possiblities for each of 3 positions, the number of possible codes is 2^3 = 8. Your code is one of those, so its probability of occurrence is 1/8.
