Answer : The final pressure in the two containers is, 2.62 atm
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

Thus, the expression for final pressure in the two containers will be:


where,
 = pressure of N₂ gas = 4.45 atm
 = pressure of N₂ gas = 4.45 atm
 = pressure of Ar gas = 2.75 atm
 = pressure of Ar gas = 2.75 atm
 = volume of N₂ gas = 3.00 L
 = volume of N₂ gas = 3.00 L
 = volume of Ar gas = 2.00 L
 = volume of Ar gas = 2.00 L
P = final pressure of gas = ?
V = final volume of gas = (4.45 + 2.75) L = 7.2 L
Now put all the given values in the above equation, we get:


Thus, the final pressure in the two containers is, 2.62 atm

Yes, the water in the cup have the same average kinetic energy as the ocean, because I focus on the word 'average'. However the cup of water have less INTERNAL energy than the ocean.
hope it helps☺☺
