Answer:

Step-by-step explanation:
-This is a binomial probability distribution problem.
-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

#We substitute the given parameters in the formula to solve for variance:

Hence, the sample variance is 1.32
Since videos are 3 dollars since 1 times 3 is 3, 3 times 15 would be 45 dollars worth of videos. So you could purchase 45 songs after buying 15 videos.
