First you have to take the whole number (43) and then take the decimal and put it over 100 (77/100).
1. Divide both sides by 2
2. Add 16 to each side
Answer x > -2
20 total marbles....7 are green
probability on first draw is 7/20...and since the marble was not replaced, the probability on the second draw is 6/19. And since they cant happen at the same time, we multiply
7/20 * 6/19 = 42/380 which reduces to 21/190
