To predict how many free throws you will make, you can use proportions:
If there is a 45% probability that you make a free throw, you will write this as
45
100
Use this ratio to solve for how many free throws you will make out of 260.
45 x
100 = 260
You can use cross products to solve for x.
260 x 45 = 100x
11700 = 100x
100 100
x = 117 free throws
You can expect to make 117 free throws.
