The slope of the line is -2/3
Height of the stack = 3 fourth of an inch
=
× (1 inch)
Height of 180 cards =
× (1 inch)
Thickness of 1 card =
×
× (1 inch)
=
× (1 inch)
In the 500 spin test, 4 was chosen 121 times. This mean it was chosen 121 times out of 500, or 121/500.
Now, we need to convert this into a percent. We do this by dividing the numerator by the denominator, and multiplying the result by 100.
121/500 * 100 = 24.2, so the probability of spinning a 4 is 24.2%.
