Answer 1

Answer:

x/18 since 6 more balls are added

Answer 2

Answer:

So, let us check the conditions one by one. (1) Here, we are asked to find the probability of drawing a black ball from the bag containing 12 balls in which x balls are black. Therefore, the probability that the randomly drawn ball is black will be x12. Hence, the value of x is 3.
