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%.

x = 100°
In a parallelogram all the interior angles must add up to 360°
Opposite angles of a parallelogram are equal
360° = x + x + 80° + 80°
360° = 2x + 160°
2x = 200°
x = 100°
Alternatively:
x and 80° are corresponding angles because they are on the same line that crosses two parallel lines. Corresponding angles are complementary and add up to 180°.
180° = x + 80°
x = 100°

Hello,
The answer is C: 3x^2 - 10x - y.

Answer:
275
Step-by-step explanation:
Cross multiply
36% of the boys = 99
100% of the boys = x
36/100 = 99/x ===> 36x = 99*100 ===> 36x = 9900 ===> x = 9900/36 ===>
x = 275 boys
