The total number of students surveyed is 30.
P(2) is the probability of picking a card that says "2" out of the total number of cards.
P(2) = Frequency of 2 / Total number of students
P(2) = 12 / 30
P(2) = 0.4
Therefore, the probability of picking a card that says "2" is 40%.
So, the correct answer is 40%.
Thirty students were surveyed about the number of siblings they have. Their results were recorded and placed on a card face down.
