Question

in a bag there are balls numbered 1 - 50 find the probability of getting an odd number​

Answer 1

Answer:

So, total number of possible outcomes from three successive draws with replacement = (50 * 50 * 50) = 125000.

We have 50 balls; numbered 1 through 50. So, there are 25 even numbered balls and 25 odd numbered balls.

So, combining Case-1 and Case-2, there are (4 * 15625) = 62500 possible outcomes.

Therefore, the probability = (62500 / 125000) = (1 / 2) = 0.5.
