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
Answer:
-21.1 and 24.1
Step-by-step explanation:
-8.2*4 + 3.9*3=-21.1
5.1*3 - (-2.2*4)=24.1
[ (12 - n)/7 ] = -1
12- n = -7
-n = -19
n = 19
1x24, 2x12, 3x8 are 3 ways that get 24
