There are winnings of $50 ( 60% ), $100 ( 20% ) and $1,000 ( 2% ).
$50 * 0.6 = $30
$100 * 0.2 = $20
$1,000 * 0.02 = $20
$30 + $20 + $20 = $70
Answer: The expected payout per fan is $70.
Answer:
The probability that the maximum number of draws is required is 0.2286
Step-by-step explanation:
The probability that the maximum number of draws happens when you pick <em>different colors in the first four pick</em>.
Assume you picked one sock in the first draw. Its probability is 1, since you can draw any sock.
In the second draw, 7 socks left and you can draw all but the one which is the pair of the first draw. Then the probability is 
In the third draw, 6 socks left and you can draw one of the two pair colors which are not drawn yet. Its probability is 
In the forth draw, 5 socks left and only one pair color, which is not drawn. The probability of drawing one of this pair is 
In the fifth draw, whatever you draw, you would have one matching pair.
The probability combined is 1×

<h3>What is Internal Validity? </h3>
Internal validity can be described as the extent that a particular study can bring about the establishment of a trustworthy cause-and-effect relationship which can be set between the treatment as well as the outcome.
In conclusion, Internal validity let us understand that a study can makes it possible to eliminate alternative explanations as regards finding, hence The types of validity that were not established in this study is internal validity and the Reasonably not met are: external, construct, statistical.

Answer:
The slope is 4, and the y-intercept is Negative five-halves
Step-by-step explanation:
we have

This is the equation of the line in standard form
Convert the equation in slope intercept form

where
m is the slope
b is the y-intercept
Isolate the variable y
Subtract 8x both sides

Divide by -2 both sides

therefore
