Answer: 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
To multiply fractions, one must multiply "top by top and bottom times bottom".
Ex.
1/2*2/4=2/8=1/4
I hope this helped!
