Using AND, OR, NOT, NAND, NOR gates construct a circuit for the following problem

7. One of the more interesting public works problems is the “Superbowl” problem. At

the beginning of halftime during the Superbowl, 35 million toilets are flushed almost

simultaneously. The resulting loss of water pressure wreaks havoc on many

municipal water systems. Here you will solve the problem for a “three toilet” system.

Devise a logic circuit whose “1” inputs represent “flushes” and whose “1” outputs

represent opened water-feed valves. If no more than one toilet is flushed, that toilet’s

water valve opens, and the others remain closed. If more than one toilet is flushed,

all the water valves remain closed.

2. Relevant equations

I Made a table of Values, but i have been banging my head against my desk for now designing various circuits, here is the link to the circuit builder

Here is the Table that i came up with

IN OUT

011 000

100 100

101 000

110 000

111 000

Any Help is GREATLY Appreciated, thank you so much!
