Directions: Each question below is followed by two statements I and II. You have to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer.
One ball is drawn at random from a bag. What is the probability that the ball drawn is white in color?
I. The bag contains black and white balls in the ratio 3: 4 respectively.
II. The number of black balls is two less than the number of white balls.
1
If the data in statement l alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.
2
If the data in statement II alone is sufficient to answer the question, while the data in statement l alone is not sufficient to answer the question.
3
If the data either in statement l alone or in statement Il alone is sufficient to answer the question.
4
If the data given in both statements I and II together is not sufficient to answer the question.
