Suppose you have a weighted coin in which heads comes up with probability 3/4 and tails with probability 1/4. If you flip heads, you win $2, but if you flip tails, you lose $1. What is the expected win of a con flip in dollars

The expected win of a coin flip in dollars is 1.25.

Step-by-step explanation:

To find the expected win of a coin flip, we multiply the probability of each outcome by their earnings, and then add them.

We have that:

3/4 probability of heads. If heads, you win $2.

1/4 probability of tails. If tails, you lose $1.

What is the expected win of a coin flip in dollars?

The expected win of a coin flip in dollars is 1.25.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
