18 is C because,

You find the probability for P(six),P(no six) which is 5/36 but then you add the probability for P(no six), P(six) which is 5/36

By adding the two you get 5/18, the question only one six and there are two ways of rolling that

22 is B because

25 ($Australian) * (Conversion to Euro) 0.62 = 15.50 Euro
then convert Euro in Vistabella dollars

15.5 (Euros) * 1.44 ( Coversion to Vistabella) = $22.32

Dont doubt me again :)

It can be in any order (i.e. 6 first, then any other no., or any other no. first, then 6) so you have to do:
(5/6*1/6) + (1/6*5/6)

so i think the answer was 5/18

ok

tree diagram


1 there is one chance to get one 6
2 there is one chance to get one 6
3 there is one chance to get one 6
4 there is one chance to get one 6
5 there is one chance to get one 6
6 there are 5 chacnes to get a 6 by it self

therefore there are 10 chances out of a possible 36 to get a six by it self.
i probably didnt explain it right but i know its right

You converted the wrong way "a_ person", A Vistabella dollar is worth more than the euro, not less, get the chip off your shoulder.

25 austraian x .6.2 = 15.5 euro i agree there
but
15.5 / 1.44 give yous 10.76
you cant have it bigger then 15.5 because euros are worth more than vistabella

i'm going to doubt u on 22.

25AUD*0.62(euro)
= 15.5 euro

1 $V is worth 1.44 euros, therefore

15.5euro/1.44
= 10.76 Vistabella

14 A
19 B

21 can not be A as it is a hyperbola function, it moves away from the y-axis not to it :)
