The transistor is in saturation, so that its V C E is about 0.2V. Assuming the LED is white, its V F is about 3V. From these, you can calculate the base current I B = 9 V − 0.6 V 220 k Ω and collector current I C = 9 V − 0.2 V − 3 V 330 Ω, and then find β = I C I B. If you find a transistor whose datasheet β F is larger than this value, then the circuit will work as advertised (once the transistor goes into saturation, its β will drop to the calculated value).
