Theoretical probability is the number of ways something can happen that you consider a success divided by the number of ways that it can happen at all.
So, for this problem, there are a couple of ways to look at it depending on how precise an answer is required.
You could say that a random person is born in one of 12 months, but a success for this experiment is being born in January, June, or July, the three months that have names that begin with the letter 'J', so  .
Or, you could say that a random person is born on one of 365 days, 92 of which occur in the three 'J' months, so 
Or, you could account for leap years by saying that a year is approximately 365.25 days long, so so 
Pick up the phone, call your child's teacher, and make the observation that if the teacher is going to teach mathematics, the teacher needs to learn to be more specific when s/he asks a question.
