Answer:
1/11 = 0.09
Step-by-step explanation:
problem best done with a tree diagram. let's focus on the blue branch for child 1. the probability of child 1 getting a blue marble is 4/12. now since he's choosing randomly and we assuming that after giving it away, there is 12-1=11 marbles left, the second child will have the probability 3/11 of getting a yellow marble. multiple those probabilities
4/12 × 3/11
1/3 × 3/11
3/33
1/11
Hello :
the line has a equation : y = ax (<span>a y intercept at (0,0))

the equation is : y = (-1/3)x

Answer:
Let say 75% of cars older than age = Y years
than 25 % cars of age less than Y Years
Z score corresponding to 25 % = -0.674
Z score = (Value - Mean) /SD
Value = Y
Mean = 8
SD = 3.2
Z score = -0.674
-0.674 = (Y - 8)/3.2
=> Y =5.84 Years
=> Y ≈ 5.9 Years
Approximately 75% of cars driven by company employees are older than about 5.9 years
