# Binomial distribution

Thank you for your help on the other questions. Your work was easily understood.

Here are two questions that I need help on.

1) LaDonna asks a question in class 4 days out of 5 and Jason asks a question in class 1 day out of 5. What is the probability that one of them will ask a question in class on any given day? (Could you show work so I know how to do other questions?

2) If you have a normal quarter and toss it 40 times, what is the probability that it will come up heads 10 or more times? (Could you show work as well so I can understand it better?)

Thank you again!
