The experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

<h3>What is Experimental Probability?</h3>

Experimental probability is a probability that is determined on the basis of a series of experiments. A random experiment is done and is repeated many times to determine their likelihood and each repetition is known as a trial. The experiment is conducted to find the chance of an event to occur or not to occur.

Here , Favorable Outcome = 19

Total outcomes = 20

Probability = Favorable Outcome/ Total Outcome

= 19 / 20

= 95%

Thus, the experimental probability that in a group of 4 students, at least one of them has brown eyes is 95%.

AVprozaik [17]

If they drove a total of 5,300 miles in 2 days, and on the second day they drove 10 more miles then the 1st day.

5,300 ÷ 2 = 2,650

they drove 10 miles less on the first day

2,650 - 10 = 2,640

They drove 2,640 miles on the first day.

Hope this helps. :)

Define the function

miss Akunina [59]

Given that

$g(x) = x^3 + x$

the inverse $g^{-1}(x)$ is such that

$g\left(g^{-1}(x)\right) = g^{-1}(x)^3 + g^{-1}(x) = x$

or

$g\left(f(x)\right) = f(x)^3 + f(x) = x$

Differentiating both sides using the chain rule gives

$3f(x)^2f'(x) + f'(x) = 1 \\\\ f'(x) \left(3f(x)^2+1\right) = 1 \\\\ f'(x) = \dfrac1{3f(x)^2+1}$

Then the derivative of <em>f</em> at 2 is

$f'(2) = \dfrac1{3f(2)^2+1} = \boxed{\dfrac14}$
