I toss three coins together. The possible outcomes are no heads, 1 head, 2 head and 3 heads. So, I say that probability of no heads is What is wrong with this conclusion?

Answer :

I toss three coins together [given]

So, total number of outcomes = 23 = 8

and possible outcomes are(HHH),(HTT),(THT),(TTH),(HHT),(THH),(HTH) and (TTT).

Now, probability of getting no head = 1/8

Hence, the given conclusion is wrong because the probability of no head is 1/8 and 1/4.
