Alegbra- How can I solve #5?

Mathematics
1 answer:
iren [92.7K]3 years ago

Answer:

3

9

21

Step-by-step explanation:

For the first one use the law of total probability

B=A∩B+A'∩B

12=9+A∩B

A∩B= 3

For this one you should use demorgans law and the union formula

(A'∩B')=(AUB)'

AUB= A+B-A∩B

6+12-3=15

15'= 24-15 = 9

For this one use demorgans law again

(A'UB')=(A∩B)'

(A∩B)'= 24-A∩B= 24-3= 21
