A box contain 10 black marble, 8 white marble and 6 yellow marble. If a ball is drawn at random, what is the probability of getting black marble and white marble?
The probability of getting black marble:
"P_1=\\cfrac{10}{10+8+6}=\\cfrac{10}{24}=\\cfrac{5}{12}."
The probability of getting white marble:
"P_2=\\cfrac{8}{10+8+6}=\\cfrac{8}{24}=\\cfrac{1}{3}."
