Respuesta :

Answer: 4

Step-by-step explanation:

Answer:

If Pam surveys 12 more students, than  four of them should she expect to pick English their favorite, based on past data.

Step-by-step explanation:

Probability

Probability means possibility of  occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some  random events.

Out of 18 students 6 have English as their favorite

Therefore the  possibility expected is [tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex]

which mean out of 3 student one will choose English  as favorite.

Thus if Pam surveys 12 more students then 12/3 = 4 .

Thus Four of them should expect to pick English their favorite, based on past data.
