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
=
= 0.395
Answer:
<u>25%</u> is the percent error.
Step-by-step explanation:
Given:
The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
Now, to find the percent error.
As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
<em>The actual measure</em> = 2 million.
The estimated measure = 2.5 million.
<em>So, the error</em> =
Now, to get the percent error:
Therefore, 25% is the percent error.
