Solution

To find the mean (μ) of a probability distribution, we use the formula:

μ=(x×P(x))\mu = \sum (x \times P(x))

Where:

  • xx represents the possible outcomes (in this case, the number of bases).
  • P(x)P(x) represents the probability of each outcome.

Given the dataTo find the mean (μ) of a probability distribution, we use the formula:

μ=(x×P(x))\mu = \sum (x \times P(x))

Where:

  • xx represents the possible outcomes (in this case, the number of bases).
  • P(x)P(x) represents the probability of each outcome.

Given the

\text{Bases} (x) & \text{Probability} (P(x)) \\ \hline 0 & 0.7442 \\ 1 & 0.1739 \\ 2 & 0.0528 \\ 3 & 0.0002 \\ 4 & 0.0289 \\ \end{array}$$ Let's calculate the mean (μ): $$\mu = (0 \times 0.7442) + (1 \times 0.1739) + (2 \times 0.0528) + (3 \times 0.0002) + (4 \times 0.0289)$$ $$\mu = (0) + (0.1739) + (0.1056) + (0.0006) + (0.1156)$$ $$\mu = 0.3957$$ So, the mean of this probability distribution is **0.3957**.
