Question

A poll found that 74.7% of citizens felt the government was not working well. If seven people were randomly selected, what is the probability that all seven felt the government is not working wel? (Round to three decimal places as needed)

Answer 1

Solution:

Given that,

The probability that a citizen feels the government was not working well p = 74.7%

= 0.747

Number of people n = 7.

$\Rightarrow$ Probability that all 7 felt the government is not working well

= (0.747)7

= 0.1297

$\therefore$ The probability that all 7 felt the government is not working well as = 0.1297
