"A bag contains 5 white and 3 black balls, and 4 balls are successively drawn out and not replaced. Find the probability that they are alternatively of different colors." in Tuition/Class IX-X Tuition

Two possible orders=> WBWB or BWBW in both cases the probability is (5*3*4*2)/(8*7*6*5) so counting both the orders the probability is (5*3*4*2)*2/(8*7*6*5) =(1/7)

"If three natural numbers from 1 to 100 are selected randomly , then find the probability that all are divisible by both 2 and 3 ?" in Tuition/Class IX-X Tuition

Probability that the number is divisible by both 2 and 3== proability that the number is divisible by 6=> # of numbers divisible by 6 and < 100 = 16 Probability = (16C3)/(100C3)

Probability that the number is divisible by both 2 and 3 = probability that the number is divisible # of number divisible by 16 and < 100 = 16 so the probability is (16C3)/(100C3)
