Subtract 3 from 13 you get 10, divide that by two, you get 5, so one number is 5 and then add the three to the other 5, you get 8
The numbers are 5 & 8
Answer:
0.395
Step-by-step explanation:
The computation of the probability that none of the three shoppers purchased electronics is shown below:
So, first we have to determine the number of shoppers without considering the purchase i.e
= Total number of shoppers - electronics
where,
Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics
= 18 + 25 + 40 + 12 - 25
= 95 - 25
= 70
Now the probability is
= ![\frac{70}{95}\times\frac{69}{94}\times\frac{68}{93}](https://tex.z-dn.net/?f=%5Cfrac%7B70%7D%7B95%7D%5Ctimes%5Cfrac%7B69%7D%7B94%7D%5Ctimes%5Cfrac%7B68%7D%7B93%7D)
= 0.395
-3x+4=-8
-3x=-8-4
-3x=-12
X=-12 divided by -3
X=4
