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:
Answer: x =-7 and y =10
Step-by-step explanation:
The given system of equations :
Add equation (1) and (2), we get
Put value of x in (2), we get
hence, the solution of the given system is x =-7 and y =10.
Mean: 1 + 1 + 2 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 7 = 39/11 = 3.54.. rounded off = 3.5
Median: 4
Mode: 5
