3. Apply the weak law of large numbers to determine the necessary sample size in the following cases to have 95% confidence:

(a) For the standard binomial distribution, estimate p to three decimal places

ð ¼ 0:0005Þ if it is known that 0:1a pa0:5.

(b) For the negative binomial distribution with k ¼ 10, estimate m to two decimal places, where it is known that pa0:1.
