JEE MainMathematicsProbabilityNumerical+4 / −1
A bag contains 4 white and 6 black balls. Three balls are drawn at random from the bag. Let X\mathrm{X}X be the number of white balls, among the drawn balls. If σ2\sigma^{2}σ2 is the variance of X\mathrm{X}X, then 100σ2100 \sigma^{2}100σ2 is equal to ‾\underline{\hspace{2cm}}​.
