Random Vari X, Y both discrete and take values of 1 or 2. Probability for (X∩Y) Mathematics Assignment Help. Random Vari X, Y both discrete and take values of 1 or 2. Probability for (X∩Y) Mathematics Assignment Help.

a. Find E(Y^{2}), E(X^{2})

b. Find σ^{2 }x σ^{2 }y

c. Find P(X=1|Y=1), P(X=2|Y=2) (for this one I got 1/4 on both, I’m stuck

on a and b). Much help is appreciated!

y=1 | y=2 | ||

x=1 | 1/4 | 1/8 | |

x=2 | 3/8 | 1/4 |

## According to the ideal gas law, a 0.9921 mol sample of nitrogen gas in a 1.981 L Science Assignment Help

According to the ideal gas law, a **0.9921** mol sample of **nitrogen** gas in a **1.981** L container at **270.7** K should exert a pressure of **11.12** atm. By what percent does the pressure calculated using the van der Waals’ equation differ from the ideal pressure? For **N _{2}** gas, a =

**1.390**L

^{2}atm/mol

^{2}and b =

**3.910E-2**L/mol.

% *Hint:* % difference = 100 x (P _{ideal} – P_{van der Waals}) / P _{ideal}
