`{:("For student A",,,,,"For student B"),(underset(2)underset(darr)("Red"),underset(5)underset(darr)("Green"),underset(3)underset(darr)("Orange"),underset(0) underset(darr)("Black"),underset(5)underset(darr)("green"),underset(2) underset(darr)("red")):}`
`R_(A)=25xx10^(3)=25 k Omega R_(B)=5xx10^(2)-500Omega`
`:.` The student A picked nup the correct resistor of `25 kOmega`.

A purse contains 2 six-sided dice. One is a normal fair die, while the other has two 1s two 3s,and two 5s. A die is picked up and rolled. Because of some secret magnetic attraction of the unfair die, there is 75% chance of picking the unfair die and a 25% chance of picking a fair die. The dice is rolled and shows up the face 3. The probability that a fair die was picked up is (a) 1/7 (b) 1/4 (c) 1/6 (d) 1/24
