Guy's are normal like 6 ft and girls are normal around 5 ft
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
If 5/11 are girls, then 6/11 are boys (the total has to be 11/11, which equals 1).
Multiply the fraction of boys by the total number of students.
(6/11)*1551 = 846
Therefore, 846 of the students in the school are boys.
Answer:
b
Step-by-step explanation:
There's only 1 orange and 1 yellow
Then there are 8 sections
therefore, 2/8 or 1/4
Answer:
A. P(EC) = 0.4
B. P(E∪E) = 0.75
C. P(EC ∩ FC) = 0.25
Step-by-step explanation:
Let us calculate -:
we are given with - P(E) = 60 and P(F) =.15,
Thus , (a) 
(b) P(E∪F) = P(E) + P(F)
= 0.60 + 0.15
= 0.75
(c) 
∩
∪ 
= 
Hence , the answers are -A. P(EC) = 0.4 , B. P(E∪E) = 0.75 , C. P(EC ∩ FC) = 0.25.
