Can anyone help with an answer in this? What are the odds of 1 in 50 being selected 3 out of 12 times?

Each item out of fifty has a 1/50 chance of being selected once. A 1/50 * 1/50 chance of being selected twice and a 1*50*1/50*1/50 chance of being selected three times. Assuming you’re putting the same item back into the “pot” each time.

If the mean SAT verbal score is 505 and the standard deviation is 111… What is the probability that randomly selected student will have a score of less than 414.

I got -0.82 and looked up the z score and got 0.7910. Is that correct and do I have to do more?
