EleoNora [17]

The probability that the two balls are chosen <u>will differ by more than 2</u> is 43/45

Probability is the likelihood or chance that an event will occur.

If a box contains 10 equal-sized balls and 2 balls are chosen at random from the box, the total outcome will be expressed as:

10C_2=\frac{10!}{(10-2)!2!}\\ 10C_2=\frac{10!}{8!2!}\\10C_2=\frac{10\times 9 \times 8!!}{8!2!}\\10C2=\frac{90}{2} =45 ways

If the number on the two balls chosen will<u> differ by less than or equal to 2,</u> the expected outcomes are (1, 2), (1, 3) that is 2 outcomes

The probability that the two balls are chosen will differ by less than or equal to 2 is 2/45

The probability that the two balls are chosen <u>will differ by more than 2</u> is 1 - 2/45 = 43/45

Which observation is inconsistent with the ideal gas law.
prisoha [69]

The observation that is inconsistent with the ideal gas equation is; "When temperature is held constant and volume increases, the pressure increases."

Boyle's law describes the relationship between the pressure and volume of ideal gas. Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.

Hence, the statement that "When temperature is held constant and volume increases, the pressure increases." does not agree with Boyle's law therefore it is inconsistent with the ideal gas law.
