An example of adding probabilities common core algebra work is A fair coin is flipped four times, find the probability it will land up heads each
time.
<h3>What is probability distribution?</h3>
This is known to be a kind of function that tells one the probability of each outcome in a given items or distribution.
The probability it will land up heads each time;
P ( H₁ and H₂ and H₃ and H₄)
So p = 1/2. 1/2. 1/2. 1/2 = 1/16
Therefore, The probability it will land up heads each time is =

Answer: They had long days, over a one-third mile. People built from both ends and from the middle to the tunnels.
Explanation: from edge 2022
Based on the calculations, a good approximation for x when f(x) = 30 is equal to: B. 20.
<h3>How to write the equation?</h3>
Based on complete information, the equation for the line of best fit for the set of values in the table is given by this function below:
f(x) ≈ 1.8x - 5.4
Thus, a good approximation for x when f(x) = 30 would be determine by substituting the value of f(x) with 30 as follows:
30 = 1.8x - 5.4
30 + 5.4 = 1.8x
35.4 = 1.8x
x = 35.4/1.8
x = 20.
