A plane rises from take-off and flies at an angle of 4° with the horizontal runway. When it has gained 450 feet, find the dis
tance, to the nearest foot, the plane has flown. An airplane is at vertex B of a right triangle that has a horizontal side A C, a vertical side B C of length 450 feet, and a dashed hypotenuse A B of unknown length c that rises from left to right. Angle C is the right angle and angle A measures 4°.

Answer:
10.2% chance
Step-by-step explanation:
There are 12 peaches and 8 bananas for a total of 20 pieces of fruit.
So we can write it:
=
= .102 or 10.2% chance
For ease multiply all numerators (top numbers) together, then multiply the denominators (bottom numbers) together, and then divide.
12 * 11 * 10 * 9 = 11880
20 * 19 * 18 * 17 = 116,280
We start with 12 peaches and 20 total fruit, as we select a peach the number of peaches and total fruit goes down by one. We do this 4 times because you draw 4 fruits. If you select 1 fruit your chances of it being a peach are 12/20, each time you select a fruit the chances of it being a peach go down because you have 1 less total fruit, and 1 less peach. This is why you multiply each probability together.
