and hey I don't know the answer to 11 th question as I don't know much about miles
PS: Have a nice day :)
To find the value of f(3) we need to follow the below steps :
Step 1 : First plot the graph of f(x)
Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)
Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .
Step 4 : Now there exists two cases :
If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x
If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
If this is wrong than I guess I wasn't smart enough :)
Your expected win from this bet would be about -0.05, meaning that you can expect to lose 5 cents on each $1 bet.
To find this we multiply the probability for each bet times $1. Remember in Roulette, there are 18 red, 18 black and 2 zero spaces.
(18/38) x 1 + (20/38) x -1 = -0.05
The frequency is everyday that things happen they happen every day
5. (8, -5)
6. (-10, -10)
7. (-1, -3)
