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

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316

m∠a is 90°
