So there's 30 people or slots. The odds that Fatheya will be chosen to perform first is 1/30. But now there's one less slot.
Now with Fatema, there's 29 slots, so there's a 1/29 chance. Then combine these values by multiplying them:
1/30 * 1/29 = <em>1/870</em>
All done!

Answer:
3/8 of the pitcher of lemonade remains.
Step-by-step explanation:
They tell us that at first they had 7/8 of a pitcher full of lemonade, and they ask us to know what fraction is left if they have taken 1/2 of the pitcher of lemonade for a while, which means that it would be a subtraction between what had at the beginning and what they have taken, would be:
7/8 - 1/2 = (14 - 8) / 8 * 2 = 6/16 = 3/8
Which means that 3/8 of the pitcher of lemonade remains.
