A multiple choice question with 6 options will have a 16.7% chance of getting the answer correct, and a ratio of 1:6.
Step-by-step explanation:
You have a 1 in 6 chance of getting the answer correct, which can be represented with the fraction \frac{1}{6} .
To get a percentage, simply divide the 1 by the 6 and you will get an answer of 0.16666667. Multiply this by 100 and you have your answer.
To get a ratio, convert the fraction to a ratio making the left side of the ratio the numerator (the 1) and the right side the denominator (the 6).
After the 3rd pick we have: 4 white, 3 red and 8 black marbles.
The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143
