4 times as likely is Phillip to get exactly three heads than exactly two heads
A chance that something might exist, happen, or be true : the state or fact of being possible is called possibilities.
Possibility is the universal set whereas probability is the subset. Possibility is surer to occur than probability. Possibility has its opposite in the word impossibility whereas probability has its opposite in the word improbability.
We can find;
P (three heads) = C(8,3)(2/3)^3(1/3)^5 = 448 / 6561
P (two heads) = C(8,2)(2/3)^2(1/3)^6 = 112 / 6561
So...... 448 / 112 = 4 times more likely to get 3 heads than 2 heads
