60%

Step-by-step explanation:

There are 5 odd numbers between 1 and 10. Therefore, the ratio of odd numbers to all whole numbers between 1 and 10 is 5:10. However, the problem also mentions 4. Since 4 is one whole number, we can add it to the left side of the ratio. The ratio of odd numbers or 4 to all whole numbers between 1 and 10 is 6:10. To convert to a percentage, multiply each side by 10. We get 60:100, or 60 out of 100, which is written as 60%. Therefore, the probability of choosing a 4 or an odd number is 60%.
