Step-by-step explanation:
Im thinking it's false. 18 isn't even between 4 and 9.
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
Step-by-step explanation:
-2x=30-120
-2x = -90
=x = -90/-2
=x = +45
