I need detailed explanation, please

A bag contains ten balls: three white and seven black. Three balls are chosen at random from the bag without replacement. Let \( X \) be the number of white balls chosen. (Round your answers to five decimal places.) Find the distribution of \( X \) in table form: \[ \begin{array}{|c|c|c|c|c|} \hline X & 0 & 1 & 2 & 3 \\ \hline \text{Probability of } X & \text{\_\_\_\_} & \text{\_\_\_\_} & \text{\_\_\_\_} & \text{\_\_\_\_} \\ & \text{Preview} & \text{Preview} & \text{Preview} & \text{Preview} \\ \hline \end{array} \] Calculate the following: Find \( E(X) \) \(\_\_\_\_\) Preview Find \( \sigma^2(X) \) \(\_\_\_\_\) Preview
