The probability a students at jamal's school is in the band is 0.20. jamal wants to estimate the probability that in 3 randomly selected students, at least 2 are in the band.
to do this, he uses a simulation. he lets 1 represent a student who is in the band and 2, 3, 4, or 5 represent a student who is not in the band. he then uses a computer to randomly generate 3 random numbers from 1 to 5 twenty times. the results of these 20 trials are shown in the table.
based on this simulation, what is the estimated probability that at least 2 of 3 randomly selected students are in band?
