Question 5 part (ii)??
Thank you

5 (ii) 4 are greater than 8 so 8/12*8/12 as there are two die.
6 (i) X will be zero when all ducks are chosen: 5/7*4/6*3/5*2/4
It will be 1 when 1 geese is chosen: (5/7*4/6*3/5*2/4) Multiply it by 4 as this can be arranged in 4C1 ways.
2 when 2 geese are chosen: (5/7*4/6*2/5*1/4) Multiply b 4C2.

(iii)Probability that dog will be not attacked: 3/5*9/10(when chases ducks)+2/5*1/4(when chases geese)
Probability that chases geese and not attacked: 2/5*1/4
Divide this from the total probability calculated first.
