Respuesta :

Notice that there are 20 editorials with 0 responses and 30 with 1 response. Then, a total of 50 editorials have 1 or less responses.

Since the total number of editorials is 200, divide 50 by 200 to find the probability P(<=1)

[tex]\frac{50}{200}=\frac{1}{4}=0.25[/tex]

Therefore, the probability is 0.25.
