The probability of getting disease X (event A) is 0.65, and the probability of getting disease Y (event B) is 0.76. The probabil ity of getting both disease X and disease Y is 0.494. Are events A and B dependent or independent?
2 answers:
I would say independent since the problem doesn't state any relation between disease X and disease Y. Also I beleive if it were dependent the probability of getting both wouldn't be .494 (which is .65 *.76). It would have to be probability of event A and event B, and then divided by probability of just B
Answer:
The events A and B are independent
Step-by-step explanation:
The occurrence of disease X is not impacting the chances of occurrence of disease Y. Thus, these two events have no relation with each other.
The probability of getting both the disease X and disease Y when they both are considered as two independent events
Thus , it can be said that the events A and B are independent

Answer:Fee as a function of miles:
f(m) = 16.95 + 0.92m
140.23 = 16.95 + 0.92m
0.92m = 140.23 - 16.95
0.92m = 123.28
m = 123.28/0.92
m = 134 miles
Step-by-step explanation:
Answer:
2x+2x is 4 +3x is 12+ 1 is 13 + 3 is 15 - 2 is 13 -1 is 12
s o x = 1 5
and y= 1 2
