So we follow the format y=mx+c. we know the y intercept (c) is 2. the gradient is -1/2 which is a fraction. and then substitute

y=mx+c
y=mx+2
y= -1/2x +2

The following table provides a probability distribution for the random variable y. Y f(y) 1 0. 20 5 0. 30 6 0. 40 9 0. 10 (a) co

Vitek1552 [10]

The probability distribution table is used to represent individual probabilities

The value of E(y) is 5.0

<h3>How to compute e(y)?</h3>

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

$E(y) = \sum y * P(y)$

So, we have:

$E(y) = 1 * 0.20 + 5 * 0.30 + 6 * 0.40 + 9 * 0.10$

Evaluate

$E(y) = 5.0$

Hence, the value of E(y) is 5.0
