Orange is drawn 26 times and the total amount of tiles drawn is 50
you would make an equation, 26/50, you would do that because, you want to do the amount you want over the total amount, and you could make that to a percent if you wanted, which would be 52%. So your answer is 26/50
2 was already done correctly by the other person so i wont bother explaining! XD, the answer is 44% hope I helped!
