Question

determine the required value of the missing probability to make the distribution a discrete probability distribution
p(4)= (type an integer or a decimal.)

Explanation:

Step1: Use the property of discrete probability distribution

The sum of all probabilities in a discrete probability distribution is \(1\). Let \(P(4) = p\). Then \(0.26 + p+ 0.26 + 0.23=1\).

Step2: Solve for \(p\)

Simplify the left - hand side of the equation: \(p+0.75 = 1\). Subtract \(0.75\) from both sides: \(p=1 - 0.75\).

Answer:

\(0.25\)
