Question

1. A mutual fund company offers its clients several funds: a money market fund, three bond funds (short-term, intermediate-term, and long-term), two stock funds (moderate-risk and high-risk), and a balanced fund. The percentages of clients holding shares in a single fund are distributed among the different types of investment instruments as follows: PERCENTAGE TYPE Moderate risk stocks 25% Money market 20% High-risk stocks 18% Short-term bonds 15% Intermediate-term bonds 10% Balanced 7% Long-term bonds 5% TOTAL 100 % If a client is randomly selected who owns shares in only one fund: a) What is the probability that the selected client owns shares in the balanced fund? b) What is the probability that the same client owns shares in a bond fund? c) What is the probability that the same client does not own shares in a stock fund?

a) To find the probability that the selected client owns shares in the balanced fund:

P(\text{Balanced fund}) = \frac{\text{Percentage of clients in balanced fund}}{\text{Total percentage}} = \frac{7}{100} = 0.07

b) To find the probability that the same client owns shares in a bond fund:

P(\text{Bond fund}) = P(\text{Short-term}) + P(\text{Intermediate-term}) + P(\text{Long-term}) = \frac{15 + 10 + 5}{100} = \frac{30}{100} = 0.30

c) To find the probability that the same client does not own shares in a stock fund:
First, find the probability of owning shares in a stock fund (both moderate and high-risk):

P(\text{Stock fund}) = P(\text{Moderate-risk stocks}) + P(\text{High-risk stocks}) = \frac{25 + 18}{100} = \frac{43}{100} = 0.43

Then, find the complement:

P(\text{Not stock}) = 1 - P(\text{Stock fund}) = 1 - 0.43 = 0.57

The answers are:
a)

0.07

0.30

0.57

A nondegenerate ideal gas of diatomic molecules with a kilomolar mass of 2 kg/kmol and a characteristic rotational temperature of 86 K is adsorbed on the walls of a container, where the binding energy is 0.02 eV. The adsorbed molecules move freely on the walls, and their rotation is confined to the plane of the walls. Calculate the surface density of adsorbed molecules at 12 K if the gas pressure is 103 Pa! What result would you get at 68 K and the same pressure?
