Step-by-step explanation:
From the question we are told that
The number of times is n = 20
The probability of getting three or more heads in a row is
The probability of getting three or more heads in a row or three or more tails in a row is 
Generally given that it is a fair coin , then 
Here P(T) is probability of getting three or more tails in a row
Generally the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as

=> 
=> 
The formula is
P=Ae^rt
P ?
A 430
R 0.9/100=0.009
T time 2010-2000=10 years
E constant
P=430×e^(0.009×10)
p=470
equivalent to 5/24 is 15/72 (multiply top and bottom by 3)
answer is d. 15/72
