Ten numbered balls are placed in a box. The balls numbered 1–4 are blue and those numbered 5–10 are red. What is the probability that a ball drawn at random from the box is blue?

If 5- 10 is red and 1-4 of them are blue I would say that 7 of them are red and 3 are blue because the probility of it having more than3 would be rare an out of ordinary Hope this helps if not please tell me what the answer options are.
