Answer to Question #176067 in Statistics and Probability for Alfie Gallos

Question

Find the correct value of Y to make a valid probability distributions

Answer 1

Given Probability distribution is-

X - 1 2 3 4 5

P(x) - 0.11 0.15 0.35 Y 0.24

As we know $\sum P(x_i)=1$

$\Rightarrow 0.11+0.15+0.35+Y+0.24=1\\\Rightarrow Y+0.85=1\\\Rightarrow Y=1-0.85=0.15$
