I have just a little question about this : If I toss a coin 5 times, what is the probability of getting 4 tails and 1 head ? I think the answer is 5/32 ? Is this any good ? THanks
5/32 is correct.

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 !
Welcome to the forum.
Stay on-line. I'm just working it out.

Both of those are binomial distribution problems. What is the name of the book?
I have the result, but I do not yet know how to get it.
