a. The first part asks for how many ways they can be seated together in a row. Therefore we want the permutations of the set of 6 people, or 6 factorial,
6! = 6 5
= 30 4
= 360 2 = 720 possible ways to order 6 people in a row
b. There are two cases to consider here. If the doctor were to sit in the left - most seat, or the right - most seat. In either case there would be 5 people remaining, and hence 5! possible ways to arrange themselves.
5! = 5 4
= 20 3
= 120 1 = 120 possible ways to arrange themselves if the doctor were to sit in either the left - most or right - most seat.
In either case there are 120 ways, so 120 + 120 = Total of 240 arrangements among the 6 people if the doctor sits in the aisle seat ( leftmost or rightmost seat )
c. With each husband on the left, there are 3 people left, all women, that we have to consider here.
3! = 3 2 6 ways to arrange 3 couples in a row, the husband always to the left
Answer: Our required probability is 0.62=62%.
Step-by-step explanation:
Since we have given that
Let A be the event that all customers at home warehouse stores own their own home.
Let B be the event that all customers at home warehouse have lived at their current address for less than 5 years.
P(A) = 54% = 0.54
P(B) = 34% = 0.34
P(A∪B) = 26% = 0.26
We need to find the probability that a randomly selected home warehouse customer owns her own home or has lived at her current address for less than five years.
So, P(A∪B) is given by
Hence, our required probability is 0.62=62%.
