If Leo uses the generator, the total number of odd numbers he can get are 1, 3, and 5. Out of the 5 possible numbers, he has a 3 out of 5 chance of getting an odd number on the first try. For the next 400 however, he has that same probability of getting an odd number. So, 400 multiplied by 3/5 = 240. Leo can expect to get an odd number about 240 times out of the total number of 400 tries.
