Answer: 4 cards are left to be colored.
Step-by-step explanation:
As per given,
Fraction of total cards colored = [tex]\dfrac12+\dfrac38[/tex]
[tex]=\dfrac{4+3}{8}\\\\=\dfrac{7}{8}[/tex]
Fraction of cards left to be colored = [tex]1-\dfrac78=\dfrac18[/tex]
Total cards = 32
Number of cards to be colored = [tex]\dfrac18\times32=4[/tex]
Hence, 4 cards are left to be colored.
