a bag contains 6 black and 8 white balls . one ball is drawn at random . what is the probability that the ball drawn is white ?
"let number of balls = ( 6 + 8 ) = 14 . number of white balls = 8 . p ( drawing a white ball ) = 8 / 14 = 4 / 7 . option b ."
divide(add(divide(divide(factorial(8), factorial(subtract(8, const_2))), factorial(const_2)), divide(divide(factorial(6), factorial(subtract(6, const_2))), factorial(const_2))), divide(divide(factorial(add(6, 8)), factorial(subtract(add(6, 8), const_2))), factorial(const_2)))
