Question

The probability that a patient will recover from a certain blood disease is 0.4. If 15 people are known to have contracted this disease, what is the probability that at most 5 people will survive? Upload a file with your answer and the complete procedure.

Answer 1

We are given that

`\begin{gathered} p=0.4 \\ n=15 \end{gathered}`

We want to find

`p(X\leq5)`

Solution

From the question

`\begin{gathered} n=15 \\ p=0.4 \end{gathered}`

The probability is a binomial probability distribution.

Using the statistical table

`p(X\leq5)=0.403`
