Binomial Distribution, Statistics Question

[From: ] [author: ] [Date: 11-10-22] [Hit: ]
A basketball player attempts 20 shots in a game. His success rate is 35% of his shots. What is P(x>11) using binomial distribution?I got the answer as 0.19579 ........
My professor gave us this problem to solve using Excel for extra credit. I just want to make sure I have the answer correct.

A basketball player attempts 20 shots in a game. His success rate is 35% of his shots. What is P(x>11) using binomial distribution?

I got the answer as 0.19579 ... Is this correct?

-
P( x > 11) = 0.019579

In Excel I did this

= 1 - BINOM.DIST(11,20,0.35,TRUE)


This "BINOM.DIST(11,20,0.35,TRUE) " gives me P(X < 11)

I then use the complement rule

P(X > 11) = 1 - P(X < 11)

which is given by


= 1 - BINOM.DIST(11,20,0.35,TRUE)


So P(X > 11) = 0.019579

You're welcome.
