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 =

The tension in the string an instant before it broke is; T = 0.86 N
<h3>What is the Tension in the string?</h3>
We are given;
mass of ball; m = 60 g = 0.06 kg
Length of string; L = 70 cm = 0.7 m
Height the ball reaches; h = 150 cm = 1.5 m
From Newton's equation of motion;
v² - u² = 2as
where v = 0 m/s Thus;
-u² = 2(-9.81 * (1.5 - 0.7)
u² = 15.696
u = √15.696
u = 3.17 m/s
Thus, tension is;
T = mu²/L
T = (0.06 * 3.17²)/0.7
T = 0.86 N
