If x is negative, then 10-x must be positive.
for example: let's say x=-1. then 10-(-1)=11
Factors of 40: 1,2,4,5,8,10,20,40
Factors of 60: 1,2,3,4,5,6,10,12,15,20,30,60
Greatest common factor of both is 20.
3 times 100 is 300. 2 times 10 is 20. Since there is a 9 in the ones place, the number must be 329.
Answer: P(none of them Europeans play against each other)=
Explanation:
Since there are 8 teams in which 3 are Europeans.
So, remaining 5 teams are not Europeans
We have to take 2 teams to pair up.
And we have a condition that neither of team is European.
So the favourable outcome =
and the total outcomes=
So, by using theprobability formula i.e.
P(E)=
P(getting none of European team play against each other)=
=
=
