Does the choice of the base affect the perimeter of a triangle?

forsale [732]

No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.

The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.

So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.

In a lottery game a player wins $1,000,000 with probability 0.0000005, wins $200,000 with probability0.000002, and wins $30,000

MariettaO [177]

Answer:

$X_1 = 1000000 , P(X_1)= 0.0000005$

$X_2 = 200000 , P(X_2)= 0.000002$

$X_3 = 30000 , P(X_3)= 0.00001$

$X_4 = -2, P(X_4) = 1-0.0000005-0.000002-0.00001= 0.9999875$

And then replacing we have this for the expected value:

$E(X) = 1000000*0.0000005 +200000*0.000002+30000*0.00001 2*0.9999875$

And after do the math we got:

$E(X) = -0.79998$

And then the expected value for this game is -0.79998 a negative result means NOT a win.

Step-by-step explanation:

For this case we can define the random variable X as the amount that we can win. We can find the expected value with the following formula:

$E(X) = \sum_{i=1}^n X_i P(X_i)$

And we have the following probabilities and possible values given:

$X_1 = 1000000 , P(X_1)= 0.0000005$

$X_2 = 200000 , P(X_2)= 0.000002$

$X_3 = 30000 , P(X_3)= 0.00001$

$X_4 = -2, P(X_4) = 1-0.0000005-0.000002-0.00001= 0.9999875$

And then replacing we have this for the expected value:

$E(X) = 1000000*0.0000005 +200000*0.000002+30000*0.00001 2*0.9999875$

And after do the math we got:

$E(X) = -0.79998$

And then the expected value for this game is -0.79998 a negative result means NOT a win.
