A box contains 6 red marbles numbered 1 through 6 and 4 white marbles numbered from 12 through 15. Find the probability that a marble drawn is (i) white (ii) white and odd numbered (iii) even numbered (iv) red or even numbered.

Explanation

To solve the problem step by step, we will calculate the probabilities for each part of the question.

### Given:
- Total red marbles = 6 (numbered 1 to 6)
- Total white marbles = 4 (numbered 12 to 15)
- Total marbles = 6 (red) + 4 (white) = 10 marbles

### (i) Probability that a marble drawn is white:
