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:

$\frac{5}{18}$
