What answers?

Answer 2

Q14 (c) and (d)

Answer 3

You mean 14 i and ii? There's no (c) and (d).

I got 1/25 for i and 1/5 for ii

Answer 4

Oh wait. Q13 (c) and (d)

Answer 5

And how you got that for Q14?

Answer 6

13C I got 10/16 and 13D I got 14/16

Answer 7

Oops meant 1/5 for 14 i

Answer 8

There are 25 possibilities right? 0 then 0, or 0 then 1, or 0 then 2 etc. 5 of them have the same number on both days: (0,0), (1,1), (2,2), (3,3), (4,4). So the probability is 5/25=1/5.

Answer 9

Same idea with 14 ii. There are 25 possibilities. 5 of them have a total of 4: (0,4), (1,3), (2,2), (3,1), (4,0)

Answer 10

I got right for 13(c).

Answer 11

And for (d) too

Answer 12

I don't get 14 one. Sorry. :/

Answer 13

Make a probability tree with all the possibilites if you want. Like this, except there should 0,1,2,3,4 at the end of each of the 5 branches.



You can see there are 25 possibilities. How many of them have the same number on each day?
