Answer:

1/24 chance

Step-by-step explanation:

To begin you would need to find the probability of picking a green sock which would be 3/9; and you could simplify this to 1/3.

After that you need to find the probability of picking a purple sock out of the 8 left, which would provide you with 1/8. To find the probability of both you would multiply 1/8 by 1/3 to find the combined probability which would leave you with 1/24.

Find the interest principle 8000 rate .06 compounded annually years 3
HACTEHA [7]

Answer:

Step-by-step explanation:

S=P(1+ i) ^n

i= nominal rate of interest / number of compounding periods
