The probability of rolling a 5 and rolling an odd number on a die is independent; rolling a 5 does not influence the probability of rolling an odd number the next time.
King or Jack is mutually exclusive; they cannot both happen at the same time.
Club or Queen is not mutually exclusive; they can happen at the same time.
King or Ace is mutually exclusive; they cannot both happen at the same time.

Answer:
y = 5
Step-by-step explanation:
The given points lie on the horizontal line ...
y = 5
__
You could write this as 0x+1y=5, but the conventions regarding coefficients of 0 and 1 would have this simplified to y=5.
(3x + 1) + 44 = 90
(3x + 1) = (90 - 44) = 46
3x = 45
x = 45 / 3
x = 15
Answer:
Imaginary
Step-by-step explanation:
I think boys =18
girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
y=(1/5)*z*2
into 3y-2x=0 and z=30
z=30 so x=(1/10)*30*6=18
y=(1/5)*30*2=12
