Answer:
93.32% probability of obtaining a value less than or equal to -7.
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the likelihood of obtaining a value less than or equal to -7?
This is the pvalue of Z when X = -7.
So




has a pvalue of 0.9332.
So there is a 93.32% probability of obtaining a value less than or equal to -7.

6 possible ways to order 3 couples in a row
Given,
We have three married couples. that is six persons in total.
a, b, c, d, e, f may taken as the six persons.
Considering the statement:
Elder partner on the left, assume a, c and e as elders.
Then we have, (a, b) ------ ( 1)
(c, d) ------ (2)
(e, f) ------ (3)
There is no change in position between the couples.
So, we get three persons in total.
Possible ways to order these three persons will be like this: 3! = 3×2×1
= 6
