Probability of boxers winning in 10,50,100 matches. Binomial

  1. In the final match a boxer is facing another boxer and is expected to win 48% of the time. In reality they win 80% of the time.
What is the probability of that occurring in 10 matches?
2) In the very next match (in a different tournament), the boxer who won the previous match only wins 40% of the time.
- With the winning rate in the previous match, whats the probability of seeing that winning rate in 10 matches?

How would you go about this problem? I believe this a binomial problem but i do not know what the 48% and 80%. Also, how could I calculate this on excel. So if someone could guide me through this that would be great
