    For the hypothesis testing question, i still don't understand how to worked out that 'k' was 13????
    also what p(x<=???) would you write down to compare it to the significance level % to reject the null hypothesis?? as you would need to compare it at the end, right????
    I'm so confused!!!!
    Please can somebody explain it to me.
    Thanks!
    At a 10% significance level, none of the results would have resulted in H0 being rejected because P(X<=0) = 0.1216. So to reject H0, the significance level would have to be more than 12.16% so that 0 was in the critical region. But it asked for an integer value so it had to be rounded up to 13% as 12 is too small and would not reject it. I hope that all made sense If any of it didn't, let me know

    Alright so pretty sure question 1 for me is wrong lol
    But for your part 2, I don't think you've taken into account them drawing...I did 1-(0.2*0.2*0.2) = 0.992
    That would the p(Not-losing all 3. You had to do 3(WWD)+3(WDW)+3(DDW)+DDD+WWW.
