Answer:
The best prediction of the number of players in the league that have two or more siblings is 200.
Step-by-step explanation:
On a soccer team, 5 out of 13 players surveyed said they had two or more siblings.
Let A be the event that the randomly selected player has two or more siblings.
So, [tex]P(A)=\dfrac{5}{13}[/tex]
The expected value is the sum of product of each of the possible outcomes and the probability of the outcome occurring. Mathematically,
[tex]E(X) =\sum x\cdot P(X = x)[/tex]
So, here the number of players in the league that have two or more siblings will be,
[tex]E(X) =520\times \dfrac{5}{13}=200[/tex]
