Correct Answer: 4/15

Step 1: Understand that a month with 30 days has a total of 30 days.
Step 2: Identify the weekend days in a week, which are Saturday and Sunday.
Step 3: Count the number of weekends in a 30-day month. Typically, there are 4 Saturdays and 4 Sundays.
Step 4: Add the number of weekend days together: 4 Saturdays + 4 Sundays = 8 weekend days.
Step 5: Calculate the probability of choosing a weekend day by dividing the number of weekend days by the total number of days in the month: 8 weekend days / 30 total days.
Step 6: Simplify the fraction 8/30 to get 4/15.
Step 7: Recognize that 4/15 is approximately equal to 1/3.
