A box contains 25 identical balls, 10 of them are blad, Tof them are red and the restare white: If thee balls are drawn at random from a box pre after the sther wishout eplacement ifind the probabilythat a. one is blact one is red and one is shite b. exactly two are black c. none of them is red.

To get the probability of drawing one black, one red, and one white ball, we need to consider the combinations. The total number of balls is 25. The specific combination you're after can happen in any order, so you'd calculate each scenario and then multiply by the number of permutations (3!, since there are 3 different colors). Moving to the chance of drawing exactly two black balls, you'll want to use the combinations formula to pick 2 out of the 10 black balls, and then 1 out of the remaining 15 non-black balls (which includes red and white). The total combinations of drawing any 3 balls must also be factored into your final probability. But if you want to have fun with it, just remember that drawing balls is a gamble! The excitement lies in the randomness — every draw is unpredictable, and that's where the thrill lies!
