Question

use the frequency table to find the probability of five or more responses received to this week's newspaper editorials.

Answer 1

Answer:

option-B

Step-by-step explanation:

we have to find probability for 5 or more

Calculation of p(5):

number of editorials having 5 responses is 16

total number of editorials =200

so, we can find probability

$p(5)=\frac{16}{200}$

$p(5)=\frac{2}{25}$

Calculation of p(=>6):

number of editorials having 6 or more  responses is 6

total number of editorials =200

so, we can find probability

$p(=>6)=\frac{6}{200}$

$p(=>6)=\frac{3}{100}$

Calculation of p(=>5):

we can use formula

p(>=5)=p(5)+p(=>6)

we can plug values

$p(=>5)=\frac{2}{25}+\frac{3}{100}$

$p(\geq5 )=\frac{11}{100}$

$p(\geq5 )=0.11$

so, answer is option-B
