2bit asynchronous binary counter in Multisim
In real life these chips are not guaranteed to always start up in the same state, you need to reset them after powering on. This is what the CLR and PR pins are for. To get Q=0, you need to put PR=1 and CLR=0. Then put CLR=1 and use the chip.

Normally you could use a RC circuit to provide the reset pulse from the power supply, but in Multisim that may not be an option, so just connect a button or something so that you can reset your circuit after powering it on..
