Respuesta :

We are given that

[tex]\begin{gathered} p=0.4 \\ n=15 \end{gathered}[/tex]

We want to find

[tex]p(X\leq5)[/tex]

Solution

From the question

[tex]\begin{gathered} n=15 \\ p=0.4 \end{gathered}[/tex]

The probability is a binomial probability distribution.

Using the statistical table

[tex]p(X\leq5)=0.403[/tex]
