Answer :
Answer:
If five fair coins are flipped, the probability that all five of them land on heads is 0.03125
Explanation:
You can think of this as a tree of possibilities. For the first flip there are two branches - heads or tails. At the end of these branches, the next flip gives another two possibilities - so add two new branches to the end of the previous 2 branches. Now we have 4 end branches. For the third flip, add two more branches at the end of the existing 4 end branches. Now we have 8 end branches... etc.
