I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.

Assume a binomial distribution. Then the mean of the distribution is , where is the number of people taken in a sample and is the probability of the mutation occurring in any given person, and the standard deviation is . Then in this case, the standard deviation is .
