Durito , Ganch or anyone.... Math question

[rake922]

I forget how to do this...

Let's say there's a 33.333% chance of team A winning


With that above statement

What's the probability of them winning ...


A. 7 of 15 times
B. 8 of 15 times
C. 9 of 15 times
D. 10 of 15 times


What's the probability of them losing:

E. 13 of 15 times
F. 12 of 15 times

If somebody knows how to do it, and how I can do it an excel, I'd appreciate it

In Excel, the probabilities of the team in question winning or losing exactly the number of times specified:

1. =BINOMDIST(7, 15, 33.333%, 0)
2. =BINOMDIST(8, 15, 33.333%, 0)
3. =BINOMDIST(9, 15, 33.333%, 0)
4. =BINOMDIST(10, 15, 33.333%, 0)
5. =BINOMDIST(13, 15, 66.667%, 0)
6. =BINOMDIST(12, 15, 66.667%, 0)

In general the probability of winning exactly W games out of N given a single-game win probability of p is:

=BINOMDIST(W, N, p, 0)

And the probability of winning at least W games out of N given a single-game win probability of p is:

=1-BINOMDIST(W-1, N, p, 1)

[durito]

a) 11.11%
b) 5.48%
c) 2.1%
d) .62%

you can use binomdist function in excel

nm, ganch is a machine
