问题如下:
Which of the following is a continuous random variable?
选项:
A. The value of a futures contract quoted in increments of $0.05
B. The total number of heads recorded in 1 million tosses of a coin
C. The rate of return on a diversified portfolio of stocks over a three-month period
解释:
C is correct.
The rate of return is a random variable because the future outcomes are uncertain, and it is continuous because it can take on an unlimited number of outcomes.
