Answer:
We can not choose a senator again from the state from where we have already chosen a senator.
There are 2 number of ways we can chose a senator from the one chosen state.
Total number of ways of making the 3 senator committee = 940800
Step-by-step explanation:
Given that There are 2 Senators from each of 50 states.
To find:
The number of ways to make a 3 senator committee so that no two members are from the same state = ?
Solution:
There are a total of 2 50 = 100 senators
First of all, we can select any one from these 100.
So, number of ways of choosing the first senator = 100 (50 states left and there are 2 senators so 50 2 = 96)
Now, we need to choose the 2nd senator.
As per the given statement, we <em>can not choose the senator from the state from which we have already chosen a senator. The one state will not be considered now.</em>
So, number of ways of choosing the 2nd senator = 98 (49 states left and there are 2 senators so 49 2 = 98)
Now, we need to choose the 3rd senator.
As per the given statement, we <em>can not choose the senator from the state from which we have already chosen a senator. Two states will not be considered now.</em>
So, number of ways of choosing the 3rd senator = 96 (48 states left and there are <em>2 senators</em> so 48 2 = 96)
Total number of ways of making the 3 senator committee = 100 98
96 = 940800
