A die is thrown 4 times and getting 3 is considered a success. The probability of 2 successes is:

If $P(A) = \frac{3}{10}$, $P(B) = \frac{1}{5}$ and $P(A \cup B) = \frac{3}{8}$ then the value of $P(B|A) + P(A|B)$ is:

Which of the following statements are NOT correct about Standard Normal Distribution?

(A) The probability curve of the Standard Normal Distribution is a bell-shaped curve.

(B) The Standard Normal variate (Z) score describes the position of each data point in terms of its distance from the mean, when measured in standard deviation units.

(C) The Z-score is negative if the data point lies above the mean, and positive if it lies below the mean.

(D) There is a 95.45 % probability of randomly selecting a score between $\mu - \sigma$ and $\mu + \sigma$, when $\sigma$ is standard deviation and $\mu$ is mean.
