Question

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

Answer 1

option-B

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)=(16)/(200)`

`p(5)=(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)=(6)/(200)`

`p(=>6)=(3)/(100)`

Calculation of p(=>5):

we can use formula

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

we can plug values

`p(=>5)=(2)/(25)+(3)/(100)`

`p(\geq5 )=(11)/(100)`

`p(\geq5 )=0.11`

so, answer is option-B
