Answer:
39% chance for only boys, 61% chance for only girls for the first two questions
the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.
100:224 = 61:x, or 61/100 = x/224
Cross multiply; 100x=13664
Then, divide by 100; x=136.64, or about 137 groups would contain all girls
