Step-by-step explanation:
A+B =1/18
A+B =1/18B+C = 1/24
A+B =1/18B+C = 1/24A+C = 1/36
A+B =1/18B+C = 1/24A+C = 1/36A+B+C = 1/18 + 1/24 + 1/36
A+B =1/18B+C = 1/24A+C = 1/36A+B+C = 1/18 + 1/24 + 1/36 = (4 + 3 + 2)/72
A+B =1/18B+C = 1/24A+C = 1/36A+B+C = 1/18 + 1/24 + 1/36 = (4 + 3 + 2)/72 = 9/72
A+B =1/18B+C = 1/24A+C = 1/36A+B+C = 1/18 + 1/24 + 1/36 = (4 + 3 + 2)/72 = 9/72 = 1/8
A+B =1/18B+C = 1/24A+C = 1/36A+B+C = 1/18 + 1/24 + 1/36 = (4 + 3 + 2)/72 = 9/72 = 1/8 8 days
hope this helps you
