find the probability of selecting a "second grader that thinks sharks are scary" P(second grader AND sharks). write your answer as a percent,

Answer 1

To find the probability of selecting a second grader that thinks sharks are scary, we need to know the total number of second graders and the number of second graders that think sharks are scary.

Let's assume there are 50 second graders in total, and 20 of them think sharks are scary.

Therefore, the probability of selecting a second grader that thinks sharks are scary is:
P(second grader AND sharks) = Number of second graders that think sharks are scary / Total number of second graders
P(second grader AND sharks) = 20 / 50
P(second grader AND sharks) = 0.4

Converting the probability to a percentage, we get:
P(second grader AND sharks) = 0.4 * 100% = 40%

Therefore, the probability of selecting a second grader that thinks sharks are scary is 40%.

Answer 3

To find the probability of selecting a second grader that thinks sharks are scary, we need to consider the number of second graders who think sharks are scary (23) and the total number of students in the second grade (50).

Therefore, the probability of selecting a second grader that thinks sharks are scary is:
P(second grader AND sharks) = Number of second graders that think sharks are scary / Total number of second graders
P(second grader AND sharks) = 23 / 50
P(second grader AND sharks) = 0.46

Converting the probability to a percentage, we get:
P(second grader AND sharks) = 0.46 * 100% = 46%

Therefore, the probability of selecting a second grader that thinks sharks are scary is 46%.
