She used 5.8 pints of white paint.
8.3 (all paint) - 2.5 (blue paint) = 5.8 (white paint)

I do hope I helped you in a way! If I am incorrect I apologize.
Answer:
B) 4/5 ; likely
Step-by-step explanation:
If 2/10 (or 1/5) is the possibility of getting a red then it is likely the remaining will not be red.
So , it is likely 4/5 of the rest won't be red.
The 30º-60º-90º triangle is a special case you'd do well to remember, because the legs always occur in the same ratio to one another. As your picture shows (I'm guessing "SL" stands for short leg?), the sides labeled 4, y and x occur in a ratio of 1 to √3 to 2.
This means
sin(30º) = SL/(2*SL) = 1/2
tan(30º) = SL/(√3*SL) = 1/√3
(and also cos(30º) = (√3*SL)/(2*SL) = √3/2, though you don't really need that here)
So in this triangle, x and y satisfy
sin(30º) = 4/x
tan(30º) = 4/y
This comes straight from the definitions of sine and tangent. Then
4/x = 1/2 ==> x = 8
4/y = 1/√3 ==> y = 4√3
