SUMMARY

The discussion centers on calculating the number of possible outcomes for a stockbroker purchasing 5 different stocks, where each stock can either raise, fall, or stay the same. The correct approach involves recognizing that each stock has 3 independent outcomes. Therefore, the total number of possibilities is calculated as 3 raised to the power of 5, resulting in 243 distinct outcomes. The initial incorrect calculation of 960 was due to a misunderstanding of the independence of each stock's outcome.

PREREQUISITES

Homework Statement



A stockbroker purchases 5 different stocks. During the next month, each stock can either raise,fall or stay the same. How many different possibilities are there?

Homework Equations





The Attempt at a Solution


For each stock, there are 3 possible choices(raise,fall,same). For each of the choices, there are 4 possible outcomes. From that, i multiplied 5*3*4*4*4=960 but it's wrong. Anyone know where i went wrong with my reasoning?
