Atown recently dismissed 9 employees in order to meet their new budget reductions. the town had 7 employees over 50 years of age and 15 under 50. if the dismissed employees were selected at random, what is the probability that exactly 1 employee was over 50? express your answer as a fraction or a decimal number rounded to four decimal places.

  0.1340

Step-by-step explanation:

The binomial distribution formula is given by :-

, where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.

Given : The number of employees over 50 years of age =7

The probability of employees over 50 years of age =

Number of dismissed employees : n= 9

Now, the required probability will be :

Thus, the probability that exactly 1 employee was over 50 = 0.1340

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
