MATH PLEASE HELP

The Sorry State Lottery requires you to select 7 different numbers from 0 through 55. (Order is not important.) You are a Big Winner if the 7 numbers you select agree with those in the drawing, and you are a SmallFry Winner if 6 of your 7 numbers agree with those in the drawing. (Round all answers to three significant figures. Enter the answers in scientific notation.)
What is the probability of being a Big Winner?
What is the probability of being a SmallFry Winner?
What is the probability that you are either a Big Winner or a SmallFry winner?

Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over posts that have already been answered in another post. Thank you.
I have already answered your later post.
