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?

From the given situation, 1 represents a student who is in the band.
The probability that at least 2 out of 3 randomly selected student is in the band is given by the number of times 1 appeared more than once in the twenty trials divided by twenty.

The number of times 1 appeared more than once in the twenty trials is 2.

Therefore, the required probability = 2 / 20 = 1 / 10 = 0.1
