Question

This question has part a,b,c, and d. Second image is the description of the figure.

A teacher randomly selects 1 of his 25 kindergarten students and records the student's gender, as well as whether or nat that student had gone to preschool. (a) Construct a tree diagram for this experiment. Figure Description A tree diagram begins at a point and an upper and lower branch extend from this point to the right. From each of these two branches two more upper and lower branches extend to the right. The branches extending from the first point from top to battom are labeled ? and Female. The next set of branches from top to bottom are labeled ?, No Preschool, Preschool, and 7. The end of each sequence af branches from top to bottom are labeled E,: 7, E7,E7, and E: 2. How many simple events are there? simple events (b) The table below shows the distribution of the 25 students according to gender and preschool experience. Male Female Preschool No Preschool Lise the table to assign probabilities to the simple events in part (a). (Enter your probabilities as fractions.) RE,) - REJ - RE) - RE) - (c) What is the probability that the randomly selected student is male? (Enter your probablity as a fraction.) (d) What is the probability that the student is a female and did nat go to preschool? (Enter your probability as a fraction.)
