Re: probability
5/32 is correct.
The limit operator is just an excuse for doing something you know you can't.

Re: probability
Omg im happy to know that because in my book it says its 4/32 ?!? And here is another one, what is the prob that it will land 3 times on head and 2 times on tails ? I got 9/32 but in my book it says 8/32 ?!? There is always 1 of difference, we could say it's an error ? Thanks !

Re: probability
hi Al-Allo
Welcome to the forum.
Stay on-line. I'm just working it out.
1 5 10 10 5 1
It should be 10/32

Re: probability
Hi Al-Allo;
Both of those are binomial distribution problems. What is the name of the book?
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.
