Sagot :
Answer:
0.303
Step-by-step explanation:
The number of students who plays both flute and Piano can be obtained thus :
Let numbwr who plays both =x
Piano only + flute only + both + neither = total
12 + 1 + x + 10 = 33
23 + x = 33
x = 33 - 23
x = 10
Hence, probability that student plays both instrument :
P = required outcome / Total possible outcomes
P(plays both) = 10 / 33 = 0.303
