This is completely variable. Airplanes have been built with as few as one engine to as many as ten engines (the only airplane with this many ever built was the B-36 strategic bomber having six 28-cylinder Pratt & Whitney R-4360 'Wasp Major' radial engines and four General Electric J47-19 jet engines).

Zero.
A jumbo jet, also known as a 747, has four engines. These engines are all mounted on the wings of the plane and are needed to power the plane through height weight takeoffs.
Depending on the size of the jet, the amount of engines may vary between 2 and 4 (on most commercial aircraft) The engines can be fixed to the wings, integrated in the tail, or above the stabilizers in the rear of the plane.
A plane which has 2engines on their wings 1 is also in the Tail of the Plane same with if a planes wings had 4 engines it also has one in the Tail of the Plane
They have engines.
it has engines
A jumbo plane, such as the Boeing 747, typically has four engines. These engines provide the necessary thrust for takeoff, cruising, and landing. Some modern jumbo jets, like the Airbus A380, have four engines as well, while others, like the Boeing 777, can have two engines. The specific number depends on the model and design of the aircraft.
the engines
jet engines, turbojet engines, turbo-prop engines, four-stroke piston driven engines... Can you be more specific?
A jet plane is any aircraft powered by jet engines.
