Hey! I got 0.04 for first question and 0.038 for second question. For the last one, I use P(515,155) = 0.02 because jess only need 10 marks to win, so I don't think P(555, 551) is included here. Jess could have won after her second spin by then. But my friends said we should include the even number for the last question because EXACTLY THREE spins could be an even number as long as Jess wins, is that true???
