Expected value of the bet is
the sum of the products of value of outcome and its probability,
less the amount paid to place the bet.
Outcomes value probability
win 225 1/4
lose 0 3/4
cost of bet = 40
So expected value of bet
E[X]=225*(1/4)+0*(3/4)-40
=56.25-40
=16.25
This means that in the long run, gambler will win, since the expected value is positive. (does NOT mean she will win in the next bet!)

Answer:
I got 1.885 for the answer.
Maybe they wanted it rounded to just 2 decimal places.
Step-by-step explanation:
HI THERE!!!!!
The answer is your question is the second choice 59 in^2.
Here is how you can do it:
1. Area of rectangle = length*width = 7*4 = 28 square inches
2. Area of triangle on the top = 0.5*base*height = 0.5*7*6 = 21 square inches
3. Area of triangle on right side = 0.5*base*height = 0.5*4*5 = 10 square inches.
Now you can do the total area:
Add them all →→ 28+21+10 = 59
Hope this helps u out.;)P.S. id really appreciate brainliest thx

Answer:
sinθ = 
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = 
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ = will be the answer.
