Answer:
1/9
Step-by-step explanation:
The probability that both selected students play basketball is 1/19
1. Determine the probability of selecting the first basketball player: 5/20 = 1/4
2. Since one student has already been selected, there are 4 basketball players left out of 19 students
3. Calculate the probability of selecting the second basketball player: 4/19
4. Multiply the probabilities: (1/4) * (4/19) = 1/19
