Can any share mock paper .please friends
Hey guys, Question 6 QA (the biased coin one)
Shouldnt the probability of getting 2 heads and 2 tails be 4/81?
According to the solution, it seems that the answer sees HHTT and HTHT as being different (hence the 4C2) where as the question was only getting 2 heads and 2 tails.
Any explanations please?
