A marketing survey found that among a group of customers, the percentages of those who purchased Product X and/or Product Y are shown in the table below.
| Purchased Product Y | Did not purchase Product Y | |
|---|---|---|
| Purchased Product X | 35% | 25% |
| Did not purchase Product X | 10% | 30% |
If a customer who did not purchase Product Y is selected at random, what is the probability, to the nearest hundredth, that this customer also did not purchase Product X?
