Question

Administrators know that 50% of the students at Garden Grove Middle School ride the bus to school. Use the random number table below to conduct a simulation. Find the probability that out of 6 randomly selected students, at least 4 ride the bus to school. In the table, an even digit represents a student who rides the bus, and an odd digit represents a student who does not ride the bus. (For the purposes of this simulation, consider 0 to be an even number.) A Look at the top-left cell in the table. The digits in the cell represent 6 randomly selected students. Out of the 6 students, how many ride the bus to school? There are 40 cells in the table. Repeat the process from Part A for each of the cells. Keep track of the number of cells in which at least 4 students ride the bus to school. How many of the 40 cells did you count? Based on the simulation, what is the probability that at least 4 out of 6 randomly selected students ride the bus to school?
