Step-by-step explanation:
![x+4y-3z=1](https://tex.z-dn.net/?f=x%2B4y-3z%3D1)
![x=1-4y+3z](https://tex.z-dn.net/?f=x%3D1-4y%2B3z)
![3(1-4y+3z)+12y-9z=8](https://tex.z-dn.net/?f=3%281-4y%2B3z%29%2B12y-9z%3D8)
![3-12y+9z+12y-9z=8](https://tex.z-dn.net/?f=3-12y%2B9z%2B12y-9z%3D8)
![3=8](https://tex.z-dn.net/?f=3%3D8)
so your answer is No solution
Answer:
0.1729 = 17.29% probability that a randomly chosen mathematics degree was a master's degree given that it was awarded to a woman
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Given to a woman.
Event B: Masters degree.
21% were master’s degrees
This means that ![P(B) = 0.21](https://tex.z-dn.net/?f=P%28B%29%20%3D%200.21)
Women earned 40% of masters
This means that ![P(A|B) = 0.4](https://tex.z-dn.net/?f=P%28A%7CB%29%20%3D%200.4)
Probability of the degree being given to a women:
52% of 76%, 40% of 21% and 22% of 3%. So
![P(A) = 0.52*0.76 + 0.4*0.21 + 0.22*0.03 = 0.4858](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.52%2A0.76%20%2B%200.4%2A0.21%20%2B%200.22%2A0.03%20%3D%200.4858)
What is the probability that a randomly chosen mathematics degree was a master's degree given that it was awarded to a woman?
0.1729 = 17.29% probability that a randomly chosen mathematics degree was a master's degree given that it was awarded to a woman
