$probability=\frac{favorable\ cases}{sample space}=\frac{(1,3)(3,1)(2,4)(4,2)(3,5)(5,3)(4,6)(6,4)}{total \ 36 \ pairs}=\frac{8}{36}=\frac{2}{9}$

JEST Sample Question-6
Two gamblers have an argument. The first one claims that if a fair coin is tossed repeatedly, getting two consecutive heads is very unlikely. The second, naturally, is denying this. They decide to settle this by an actual trial; if, within n coin tosses, ... demonstrated. What happens for larger values of n? Is it true that P (n) only increases with n? Justify your answer.
