Mass of a packet = 1/2 kg x 1000 = 500 g
mass of 6 packets = 6 x 500 = 3000 g
total mass = 110 + 3000 = 3110 g
The probability of drawing a blue card is equal to the quotient when the number of blue cards is divided by the total number of cards. This is, 16/38 which is also equal to 8/19. Thus, the probability of drawing a yellow card is 8/19. The answer is letter C.
