Explanation
## Step 1: Calculate the probability of being born in March.### There are 12 months in a year. Assuming each month has an equal likelihood, the probability of being born in March is
.## Step 2: Calculate the probability of being born on a weekend.### There are 7 days in a week, and 2 of those days are weekend days (Saturday and Sunday). Assuming each day has an equal likelihood, the probability of being born on a weekend is
.## Step 3: Calculate the probability of being born in March AND on a weekend.### The probability of both events occurring is the product of their individual probabilities:
.## Step 4: Calculate the probability of being born in March OR on a weekend.### The probability of either event occurring is the sum of their individual probabilities minus the probability of both events occurring:
.## Step 5: Convert the fraction to a decimal rounded to three decimal places.###
