It's not written in English ... ^^ Even, it's only exercises, nothing more lol
oh yes you're right. i noticed i missed one, so thanks ! finaly, my book wasnt right ! thanks you two !
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 !
5/32 is correct.
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
