Answer: 1)The drivers with low alcohol in take from the breathlyser, being above the limit, A = 5/100;
2)The drivers above the alcohol limit, give reading below that level, B = 15/100;
3) The drivers above the alcohol limit that are arrested at radom by police, C = 12/100
Step-by-step explanation: a) A + B + C = 5/100 + 15/100 + 12/100 = 32/100
b) 1 - ( A + B + C) = 1 - 32/100 = 68/100
c) A = 5/100
d) 1 - 5/100 = 95/100
It is x=2 because 12 into 4 is 3 so 6 into 3 is 2
It would also be 42 because the triangle is divided in half.
2 = $1.45
1 = $0.725
