10. When Ayla plays darts the chances that she hits a bulls eye is 0.5.
[2] a) Draw a tree diagram to represent this problem when 3 darts are thrown.
[1] b) What are the chances that three darts fired in succession will all hit bulls eye?
= 0.5/3 = 0.16
[1] c) What is the probability that none will hit?
[2] d) What is the probability that at least one will hit?
[2] e) What is the probability that 2 will hit?
0.5 is the probability that it will hit a bullseye.
0.5/2 = 0.25 is the probability that 2 will hit.
I'm not sure how to answer this question or if I am doing the right thing.
Thanks a lot!
