The first choice is your answer. Since it’s substitution, you have to plug in x to the x in the bottom equation
Answer:
She poured a total of 5 5/8 in the glasses
Step-by-step explanation:
To get the total, we need to multiply the amount in each glass by the number of glasses.
1 1/8 * 5 = 5 5/8
Answer: P(none of them Europeans play against each other)=![\frac{5}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B14%7D)
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 =![\binom{5}{2}](https://tex.z-dn.net/?f=%5Cbinom%7B5%7D%7B2%7D)
and the total outcomes=![\binom{8}{2}](https://tex.z-dn.net/?f=%5Cbinom%7B8%7D%7B2%7D)
So, by using theprobability formula i.e.
P(E)=![\frac{\text{No. of favourable outcome}}{\text{Total no. of outcomes}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BNo.%20of%20favourable%20outcome%7D%7D%7B%5Ctext%7BTotal%20no.%20of%20outcomes%7D%7D)
P(getting none of European team play against each other)=![\frac{\binom{5}{2}}{\binom{8}{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cbinom%7B5%7D%7B2%7D%7D%7B%5Cbinom%7B8%7D%7B3%7D%7D)
=![\frac{5\times4}{8\times7}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ctimes4%7D%7B8%5Ctimes7%7D)
=![\frac{5}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B14%7D)
