Is this for someone in particular?? But it depends on the equation you are doing
The answers are RBR and BBR
Trust me I took the test
Let the number of boys be b, the number of girls be g and that of teachers be t,
thus:
b=kg/t
where k is the constant of proportionality
k=bt/g
b=24, when g=16 and t=2
k=(24*2)/16
k=3
hence:
b=(3g)/2
thus the number of girls when:
b=73 and t=1 will be:
73=(3*g)/1
73=3g
g=73/3
g=24.333~ 24 girls
The correct answer is B. Drawing B, C, L, M, N, R, T, or Z
Further Explanation:
Let us first define complement first.
The complement of an event is the opposite of it. For example in this case, the complement of drawing a vowel will be not drawing a vowel.
So,
Let S be the set of alphabets present on scrabble tiles
![S = \{A,B,C,E,E,E,L,M,N,O,R,T,Z\}](https://tex.z-dn.net/?f=S%20%3D%20%5C%7BA%2CB%2CC%2CE%2CE%2CE%2CL%2CM%2CN%2CO%2CR%2CT%2CZ%5C%7D)
Drawing a vowel will constitute
![\{A,E,E,E,O\}](https://tex.z-dn.net/?f=%5C%7BA%2CE%2CE%2CE%2CO%5C%7D)
So, the complement (not Drawing a vowel) will be:
![\{B,C,L,M,N,R,T,Z\}](https://tex.z-dn.net/?f=%5C%7BB%2CC%2CL%2CM%2CN%2CR%2CT%2CZ%5C%7D)
So drawing any of the consonant from the consonants present on scrabble tiles will be the complement of drawing a vowel.
Hence, Option B is correct ..

It would be D because you can't have two of the same X factors with different Y outputs
