    2.5 is the mean of this distribution.
    What is the distribution’s mean?
    • The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable’s probability as described by the distribution.
    • The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.
    Given: p = 0.05 and n= 50
    Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5
    Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.
