ok P(heads) basically mean the probabltity of head coming on a toss flip.
As it is 1, the P(tails) is 0.
P(heads) + P(tails) = 1
Hence you flip the coin 1,10 0r 1000 times, according to P(heads)=1, the tails must never occur.
Peace out.

It sounds like the coin in your problem is a 'double-sided coin', a coin in which both sides are the same. In this case, both sides must be heads.
A probability cannot be greater than 1. The sum of all probabilities must equal 1. Since you are telling us that P(heads)=1, this takes up all the possibilities. You will only be able to flip heads. This means that there is no possibility of flipping tails.
Thus, the expected number of tails is 0!
Hope this helps.

Since the P(heads)=1, the expected number of tails in 10 flips is 0, because it is heads 100% of the time.

Where'd you get the double-headed coin?
P(heads) = 1 means that it will always be heads, so the expected number of tails for any amount of flipping is 0.

Are you joking? If P(heads) =1 then there's no other possibility.
There are axioms of probability:
1. 0 <= p(x) <=1 for any event.
2, the sum of the probabilities of all possible events is 1.
So, if a coin has two possibilities and p(heads) =1 then p(tails) must be zero.

its nonetheless going to b a 50/50 substitute because of the fact a coin has 2 facets and your no longer attempting to get 9 heads in a row then a tail, your onlying attempting to get a tail on the subsequent turn

If P(heads) = 1 then P(tails) can only be 1-1=0
U must be really lucky...
