Answer
# Explanation:
## Step1: Find total number of students
Total students = 5 + 5+ 7 + 1=18
## Step2: Identify number of students who are irresponsible and have 0 siblings
Number of students who are irresponsible and have 0 siblings = 5
## Step3: Calculate probability
Probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}=\frac{5}{18}$
# Answer:
$\frac{5}{18}$
