In a certain class of students, there are 1111 boys from Wilmette, 44 girls from Kenilworth, 99 girls from Wilmette, 77 boys from Glencoe, 33 boys from Kenilworth and 77 girls from Glencoe. If the teacher calls upon a student to answer a question, what is the probability that the student will be from Kenilworth? Round your answer to three decimal places.

0.175

Step-by-step explanation:

Probability is particular about a certain outcome of an event relative to the total possible outcome in the event.

Mathematically, Probability = favourable outcome/possible outcome.

In this case, favourable outcome = number of students from kenilworth 44 + 33 = 77

Possible outcome = total number of students = 111 + 44 + 99 + 77 + 33 + 77 = 441

Hence, probability of choosing a student from kenilworth = 77/441 = 0.175 (3d.p)

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
