    The Question is this: " There are n sweets in a bag. Six of the sweets are orange. The rest of the sweets are yellow. Hannah takes a sweet from the bag. She eats the sweet. Hannah then takes at random another sweet from the bag. She eats the sweet. The probability that Hannah eats two orange sweets is 1/3. Show that n²-n-90=0 "

    I solved it: The left pic shows the Actual answer, the right pic is just an addition which the question didn't ask for, which is find the total number of sweets in the bag.
