a bag contains 6 green and 8 white balls . if two balls are drawn simultaneously , the probability that both are of the same colour is
"drawing two balls of same color from six green balls can be done in 6 c ₂ ways . similarly from eight white balls two can be drawn in ⁸ c ₂ ways . p = 6 c ₂ / ¹ ⁵ c ₂ + ⁸ c ₂ / ¹ ⁵ c ₂ = 43 / 91 answer : e"
add(multiply(divide(8, add(6, 8)), divide(subtract(8, const_1), subtract(add(6, 8), const_1))), multiply(divide(6, add(6, 8)), divide(subtract(6, const_1), subtract(add(6, 8), const_1))))
