Let the 2 red balloon be R1, R2,
3 blue balloons be B1, B2, B3, and
4 green balloons be G1, G2, G3, G4.
∴ Sample space
S = {R1, R2, B1, B2, B3, G1, G2, G3, G4}
∴ n(S) = 9
i. Let A be the event that Pranali gets a red balloon.
∴ The probability that Pranali gets a red balloon is 2/9
ii. Let B be the event that Pranali gets a blue balloon.
∴ The probability that Pranali gets a blue balloon is 1/3.
iii. Let C be the event that Pranali gets a green balloon.
∴ The probability that Pranali gets a green balloon is 4/9.
