If everything on inside of a line is 180->
(Line) --------/---------- everything on top equals 180 and there should be a number on either side. For instance 180-50 for the top would be 130, the wide angle's angle. I answer everything I like and come across so sorry I am four weeks late.

use the frequency table to find the probability of at most 4 responses received to this week's newspaper editorials.

ZanzabumX [31]

Answer:

Step-by-step explanation:

To get probability of AT MOST 4 responses means all the probabilities Equal to or Less Than 4.

From the table, that is probability of 0, 1, 2, 3 or 4. (OR in probability means adding)

Hence, we add the number of editorials for P=0,1,2,3, and 4 and then divide by total number of editorials.

$P(\leq4)= \frac{20+30+56+38+34}{200}\\P(\leq4)=\frac{178}{200}\\P(\leq4)=0.89$

Answer choice B is right.
