SUMMARY
The probability of drawing exactly 2 white balls from an urn containing 3 white and 4 red balls, with replacement, can be calculated using the binomial distribution. The probability of drawing a white ball remains constant at 3/7 for each draw due to replacement. The scenario is analogous to flipping a biased coin 5 times, where the probability of heads represents drawing a white ball. The solution requires applying the binomial probability formula to find the odds of obtaining 2 white and 3 red balls in 5 draws.
