On their first date, Kelly asks Mike to guess the date of her birth, not including the year. Complete parts a through c below. a. What is the probability that Mike will guess correctly? (Ignore leap years.) (Type an integer or a simplified fraction.)

Step 1 ：There are 365 days in a year (ignoring leap years). If Mike is guessing randomly, then there is only 1 day that is Kelly's birthday.

Step 2 ：Therefore, the probability that Mike will guess correctly is 1 out of 365.

Step 3 ：Final Answer: The probability that Mike will guess Kelly's birthday correctly is \(\boxed{\frac{1}{365}}\).
