The probability distribution table is used to represent individual probabilities

The value of E(y) is 5.0

How to compute e(y)?

The value of e(y) is calculated using the following expected value formula

[tex]E(y) = \sum y * P(y)[/tex]

So, we have:

[tex]E(y) = 1 * 0.20 + 5 * 0.30 + 6 * 0.40 + 9 * 0.10[/tex]

Evaluate

[tex]E(y) = 5.0[/tex]

Hence, the value of E(y) is 5.0
