When you're only selecting one thing from a group, a probability is just a ratio. If you're asked, say, "if you pick a random student from a class, what is the probability you pick a woman?", that is the same question as "what fraction of the students are women?" So the question here is just asking "what fraction of the bulbs are defective?" Statement 1 clearly tells us 1/61 of the bulbs are, while Statement 2 is useless.

Note also that there's a problem with the question -- the two statements can't both be true. If the ratio of defective to nondefective bulbs is 1 to 60, then the total number of bulbs absolutely must be a multiple of 61, and 720 is not a multiple of 61.
