The ratio 1:2 means there are twice as many dimes as there are quarters. An expression could be n=2d, n being number of quarters, d being number of dimes.
Probability of 2 consecutive greens equals 4/9*3/8=1/6
Probability of not getting equals 1-1/6=5/6
245 divided by 49 = 5 therefore there are 5 seats in each row.
The answer is 32
