Answer: d. 15.49
Step-by-step explanation:
Given : The random variable K has a geometric distribution with mean 16.
Formula for Mean and standard deviation in geometric distribution:
(1)
(2), where p is the probability of success in each trial.
Since (Given)
Then from (1) ,
Put value of p in (2),
Hence, the standard deviation of random variable K is closest to 15.49.
Therefore , the correct answer is d. 15.49 .
