To find the probability that a randomly selected student has a smiley given that the student got a white piece of paper, we need to consider only the white paper column in the table.
From the table, we can see that out of the total 20 white papers, there are 10 white papers with a smiley face and 10 white papers without a smiley face.
Therefore, the probability that a randomly selected student has a smiley given that the student got a white piece of paper is 10/20, which simplifies to 1/2.
Suppose for a class activity we have students who get blue, yellow and white pages of paper. Some of the papers have a smiley face and others don't. Use the table provided to find the probability that a randomly selected student has smiley given that the student got a white piece of paper.
