Answer:
1/1048576.
Explanation:
What is the probability of flipping a coin 20 times and getting 20 heads?
I'm assuming that the coin is balanced and has heads on one side and tails on the other. This means that P(head) = 1/2 and P(tail) = 1/2. 
  
P(flipping a coin 20 times and getting 20 heads)  
= (P(head))^20 = (1/2^)20  
= 1/1048576  
= 9.5367431640625×10^−7
