What are the odds of scoring a birdie(2) on all four par three holes of a standard par 72 golf?

It all depends on your experience and how skillful or lucky you are. Are you good at throwing high range? If you are your chances may not be as slim. I haven't done it, but have seen others do it. I know for a fact that they have been practicing hard and that they were committed to do so. Especially the girls in my high school they have been practicing nonstop and one of them made a hole in one! Maybe she was lucky, but it was an amazing throw! I think you will have a chance if you have faith, lots of practice, and a great group of supporters. Remember, "Anything is possible if you believe in it." Put your mind into it, your heart, and score!
Good luck and DON'T GIVE UP! KEEP DOING YOUR BEST! :)
