Question

A shipment of 10 computers contains 4 with defects. Find the probability that a sample of size 4. drawn from the 10, will not contain a defective computer,The probability is(Type an integer or a simplified fraction.)Help Me Solve ThisView an ExampleGet More Help -Clear All

Answer 1

Step 1;

`\text{Probability of any event = }\frac{n\text{umber or required outcome}}{n\text{umber of sample space}}`

Step 2:

`\text{Probability = number of required event/number of sample space.}`

Final answer

Therefore, the probability that the sample will not contain a defective computer

`=\text{ }\frac{^4C_0*^6C_4^{}}{^(10)C4}`
`\begin{gathered} =\text{ }\frac{1\text{ }*\text{ 15}}{210} \\ =\text{ }(1)/(14) \end{gathered}`
