Answer:

P(Blue)=0.60

Step-by-step explanation:

Probability: Probability\ of\ an\ event=\frac{favourable\ outcome}{total\ outcome}

Total\ marbles=20\\\\Hence\ total\ outcomes=20\\\\Blue\ marbles=12\\\\Hence\ favourable\ outcomes=12\\\\P(Blue)=\frac{12}{20}\\\\P(Blue)=\frac{2\times 6}{2\times 10}\\\\P(Blue)=\frac{6}{10}\\\\P(Blue)=0.60
