Using the binomial distribution, it is found that there is a 0.125 = 12.5% probability of observing exactly 3 tails.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, considering 3 tosses of a fair coin, the parameters are n = 3 and p = 0.5.
The probability of 3 tails is P(X = 3), hence:


0.125 = 12.5% probability of observing exactly 3 tails.

Answer:
f(x)=4x^2
f(2)=4(2)^2
f(2)=4(4)
f(2)=16
2. g(x)=4*2^x
g(2)=4*2^2
g(2)=4*4
g(2)=16
f(2)=g(2)
Both is equal to 16

Answer:
the answer is 1 2/3 - 1 3/7 ÷ (1/2+ 4/7) = 2/9
