    Because in part iii) he said from 201 to 250 so there is a different of 1 between 200 and 201 so you have to subtract 0.5 from every lower no. And add 0.5 to every upper no. (You will begin the first range from 1<x<100)

    Q6(iv) will take the range from 0.5<x<100.5 and 100.5<x<150.5 and so on Q7(a) (i) n=9 p=1/6 q=5/6 p(x>=1) = 1-(9C0 * 1/6^0 *5/6^9) ii) 1-(5/6)^n <0.9 0.1<(5/6)^n Ln(0.1)<n*ln(5/6) N>ln(0.1)/ln(5/6) n>12.6 N=13 (B) if the 3rd one is yellow = 5/8 * 4/7 * 3/6 * 2/5 * 1/4 * 3/3...
