Question

fill in the $p(x = x)$ values to give a legitimate probability distribution for the discrete random variable $x$, whose possible values are 2, 3, 4, 5, and 6.

value $x$ of $x$$p(x = x)$
30.25
40.23
50.12
60.12

Explanation:

Step1: Sum given probabilities

$0.27 + 0.25 + 0.21 + 0.12 = 0.85$

Step2: Calculate missing probability

$1 - 0.85 = 0.15$

Step3: Verify total probability

$0.27 + 0.25 + 0.21 + 0.12 + 0.15 = 1$

Answer:

The missing $P(X=6)$ value is $0.15$, so the completed table is:

value $x$ of $X$$P(X=x)$
30.25
40.21
50.12
60.15
