what is the probability of getting a number less than 4 when a die is rolled ?
"total number of outcomes possible when a die is rolled = 6 ( ∵ any one face out of the 6 faces ) i . e . , n ( s ) = 6 e = getting a number less than 4 = { 1 , 2 , 3 } hence , n ( e ) = 3 the probability = 3 / 6 = 1 / 2 . answer : b"
divide(const_2, choose(add(const_3, const_3), const_3))
