Suppose that a stock is currently selling for $100. The change in the stock's price during the next year follows a normal random
Basile [38]

Answer:

The probability that the stock will sell for $85 or less in a year's time is 0.10.

Step-by-step explanation:

Let <em>X</em> = stock's price during the next year.

The random variable <em>X</em> follows a normal distribution with mean, <em>μ</em> = $100 + $10 = $110 and standard deviation, <em>σ</em> = $20.

To compute the probability of a normally distributed random variable we first need to compute the <em>z</em>-score for the given value of the random variable.

The formula to compute the <em>z</em>-score is:

z=\frac{X-\mu}{\sigma}

Compute the probability that the stock will sell for $85 or less in a year's time as follows:

Apply continuity correction:

P (X ≤ 85) = P (X < 85 - 0.50)

                = P (X < 84.50)

                =P(\frac{X-mu}{\sigma}

                =P(Z

*Use a <em>z</em>-table for the probability.

Thus, the probability that the stock will sell for $85 or less in a year's time is 0.10.
