The random selection of a blue marble is an illustration of probability
You should expected to pull a blue marble 10 times
<h3>How to determine the expected blue marble?</h3>
The given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So we have:
Total = 40
The probability of selecting a blue marble is:
When 25 marbles are selected, the expected number of blue is:
So, we have:
Hence, the expected number of blue marbles is 10

Answer:
Please check explanations
Step-by-step explanation:
Using the difference of two squares, the lowest common multiple becomes;
1-sin^2 a
Thus, we have that;
cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a
1 - sin^2 a = cos^2 a
That means;
{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a
= 2cos a / cos^2 a
= 2/cos a
but 1/cos a = sec a
Thus;
2/ cos a = 2 sec a
