Answer:
0.4
Step-by-step explanation:
possible outcomes = 2+2+2+4=10
favourable = 4
4/10 = 2/5
2/5 = 0.4
Answer:
- probability of a false positive test result = 0.010
- The non-drug user will suffer from the result since it is positive
Step-by-step explanation:
The probability that the test result is a false positive
total number of cases studied (n) = 38 + 12 + 19 + 29 = 98
number of false positive cases ( x ) = 1
probability of false positive result = x / n = 1/98 = 0.010
The non-drug user will suffer from the result since it is positive
V=pi*r^2*h/3
=> h=3V/(pi*r^2)
V=6pi^2 cm^3
r=3 cm
h=3V/(pi*r^2)=6*pi^2 / (pi*3^2) = 2pi cm
Height = 2 pi cm
