Atwo-way frequency table shows baldness in men over 45 and men under 45.

under 45 over 45 total
bald 24 16 40
not bald 36 24 60
60 40 100

based on this data, are baldness and being over 45 independent events?

a) yes, p(bald | over 45) = p(bald)

b) yes, p(bald | over 45) = p(over 45)

c) no, p(bald | over 45) _ p(bald)

d) no, p(bald | over 45) _ p(over 45)

If , then events A and B are independent, otherwise they are dependent.

Using conditional probabilities this property can be written as:

.

Count the probabilities:

1.

2.

Then and events are independent.

correct choice is A.

Thy answer is "A) Yes, P(bald | over 45) = P(bald)"

Step-by-step explanation:

I knowith thus because me got thowest question right.

Hope thus has helped~

All thowist love, Ya boi Fraser.

angle A=72 degrees and angle B= 108 degrees

Step-by-step explanation:

1. the sum of the angles altogether must be 360 degrees

2. the picture shows that the two horizontal lines are the same and that the two vertical lines are the same

3. that means that 3y+27=5y-3

4. solve for y

5. 3y+27=5y-3

6. 27+3+3y=5y

7. 30+3y=5y

8. 30=5y-3y

9.30= 2y

10. 15=y

11. Then solve what each angle is by plugging in y

12. 3(15)+27 and 5(15)-3

13. Remember, the two should equal the same number

14. 72 degrees and 72 degrees

15. 72+72=144

16. The two horizontal lines equal 144 together which means because the whole figure equals 360 degrees, 360-144= the two vertical lines

17. 360-144=216

18. 216 equals the two vertical lines sum put together and since the two lines are equal, we cut 216 in half

19. 216/2= 108

20. each vertical line equals 108 and each horizontal line equals 72 degrees

21. Therefore angle A=72 degrees and angle B= 108 degrees

22. I know this was a lot of info. and I hope I helped you understand it!
