The probability of students choosing the left lunch line at school is p=0.431. find the variance of the binomial distribution of 982 students choosing the left lunch line today.

We are given the probability of students choosing the left lunch line at school is

We have to find the variance of the binomial distribution of 982 students choosing the left lunch line today.

Therefore, n = 982

We know that the variance of Binomial distribution is:

                rounded to 2 decimal places

Therefore, the variance of the binomial distribution of 982 students choosing the left lunch line today is 240.82

what i would say the best answer is a. 40.5

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
