1. There are 10 odd numbers and 4 + 8 + 2 + 2 + 4 + 6 + 4 = 28 total numbers. Therefore, the probability of drawing an odd number is 10/28, which can be simplified to 5/14.
2. The probability of not drawing an odd number is the same as the probability of drawing an even number. There are 18 even numbers and 4 + 1 + 2 + 2 + 8 + 4 + 8 + 6 + 4 + 8 = 47 total numbers. Therefore, the probability of not drawing an odd number (drawing an even number) is 18/47.
