To calculate this, a multiplication rule and an addition rule are used.
There are in total 20 marbles:
3 green + 4 yellow + 5 blue + 8 pink = 20 marbles.
The addition rule is used to calculate the probability of one of the events from multiple pathways. If you want that only one of the events happens, you will use the addition rule. We have two events from multiple pathways:
1. The probability that Jerome will get a green marble on the first draw is 3/20:
Of all 20 marbles, 3 of them are green. The probability that Jerome will get a green marble is 3/20.
2. The probability that Jerome will get a yellow marble on the first draw is 4/20:
Of all 20 marbles, 4 of them are yellow. The probability that Jerome will get a green marble is 4/20.
- Using the addition rule, the probability that Jerome will get a green or yellow marble on the first draw is 7/20:
3/20 + 4/20 = 7/20
The multiplication rule calculates the probability that both of two events will occur. In this method, the probabilities of each event are multiplied. Here we have two events:
1. The probability that Jerome will get a green or yellow marble on the first draw is 7/20.
2. The probability that Jerome will get a pink on the second draw is 8/20:
Of all 20 marbles, 8 of them are pink. The probability that Jerome will get a pink marble is 8/20.
- Using the multiplication rule, the probability that Jerome will get a green
or yellow marble on the first draw and a pink on the second draw is 7/50:Answer:

Step-by-step explanation:
The distance an object falls in 4 seconds is 256 feet.
Given,
The expression 16t² models the distance in feet that an object falls during t seconds after being dropped.
We need to find out what distance will an object fall in 4 seconds.
A function has an input and an output.
Example:
f(x) = x + 1
x = 1
f(1) = 1 + 1 = 2
Input = 1
Output = 2
Find the expression that describes the distance at t seconds.
= 16t²
Find the distance at t = 4.
We have,
= 16t²
= 16 x 4²
= 16 x 16
= 256
Thus the distance an object fall in 4 seconds is 256 feet.

1. it fell in 2 seconds so plug the "t" with 2
2. 16*4² ⇒ 4² = 16
3. 16*16 = 256

Mr. Powell brought home $324.16 in net pay last week. His gross pay was $594.00. Then
$594 -- 100%,
$324.16 -- x%,
or mathematically it sounds as proportion:
