However, if you decide to put some money into an investment, you are usually advised to leave it in for (at least) several years. Why? Because good years tend to cancel out bad years, giving you a better overall return with less risk. To see what we mean, let's use a 3-year moving average on the Calvert Social Balanced Fund (a socially responsible fund). 5 % Return -4.74 -2.38 (a) Use a calculator with mean and standard deviation keys to find the mean and standard deviation of the annual return for all 11 years.

It is calculated by finding the quotient of the number of favorable outcomes and the total number of possible outcomes. In symbols, n(E) P(E)= n(S) where n(E) is the number of the elements in the event and n(S) is the number of the elements in the sample space. 1. If you flip two coins, what is the probability of getting 2 heads? 2. A pair of dice is thrown, what is the probability of getting a result of prime number? 3. If a card is selected at random from a standard deck of 52 cards. What is the probability of getting a "black jack? 4. Moira collects stamps from different countries.
