1) We have that there are (52,3) ways to pick 3 cards out of 52 cards. Also, there are (4,3) ways to pick 3 kings out of the 4 total available kings in the deck. In essence, we need to have one of those ways to be the selected 3 cards. Hence, the probability is the ration (4,3)/(52,3). Computing this:
P=
The probability is very low but not negligible.
2) The Pascal triangle defines a recursive relationship. Hence, we would need to calculate all the binomial coefficients up to 51. Thus, it is not at all practical to use the Pascal Triangle to calculate the ways. It is easier to do the direct computation.

Answer:
The 95% confidence interval for the population variance is
The 95% confidence interval for the population mean is
Step-by-step explanation:
To solve this problem, a confidence interval of for the population variance will be calculated.
Then, the confidence interval for the population variance is given by:
Thus, the 95% confidence interval for the population variance is:
On other hand,
A confidence interval of for the population mean will be calculated
\Thus, the 95\% confidence interval for the population mean is:
