Question

Three-fifths of kindergarten children are bussed to school, while two-fifths of the first to fifth graders are bussed. The school has grades K through 5 and 19.4% of the students are in kindergarten. Determine the probability that a child chosen at random from the school is bussed to school.

Answer 1

60% of K children are bussed.
40% of 1-5 are bussed.
60% of 19.4 = 11.64
40% of 80.6 = 32.24
32.24 + 11.64 = 43.88%
