JEE MainMathematicsProbabilityNumerical+4 / −1
Let S = {E1, E2, ........., E8} be a sample space of a random experiment such that P(En)=n36P({E_n}) = {n \over {36}}P(En​)=36n​ for every n = 1, 2, ........, 8. Then the number of elements in the set {A⊆S:P(A)≥45}\left\{ {A \subseteq S:P(A) \ge {4 \over 5}} \right\}{A⊆S:P(A)≥54​} is ‾\underline{\hspace{2cm}}​.
