A system consists of gaseous $\mathrm{H}_{2}, \mathrm{O}_{2}, \mathrm{H}_{2} \mathrm{O}$ and $\mathrm{CO}_{2}$ where the amount of $\mathrm{CO}_{2}$ is specified and the equilibrium constant for the reaction $2 \mathrm{H}_{2}(\mathrm{g})+\mathrm{O}(\mathrm{g}) \rightleftharpoons 2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})$ is known. The number of degrees of freedom of the system is
