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.

Need help with this math

sveta [45]

This is an arithmetic sequence, as there is a common difference of 21 between terms.

By using the formula, the 18th term of the sequence is

= 1st term + (18 - 1)(21)

= 15 + 17 * 21

= 372

Solve the following equation |x+8|=2x-3

Aleks04 [339]

$2x-3\geq0\\2x\geq3\\x\geq\dfrac{3}{2}\\\\|x+8|=2x-3\\\\x+8=2x-3 \vee x+8=-2x+3\\\\x=11 \vee 3x=-5\\\\x=11 \vee x=-\dfrac{5}{3}\\\\-\dfrac{5}{3}\not \geq \dfrac{3}{2}\\\\\boxed{x=11}$
