Question

For this task, you’ll have a set of eight potential clients : Jacob, carol, Geraldo, Meg, Earvin, Dora, Adam, and Sally . You have to decide to just randomly choose two of them to offer life insurance policies. What is the probability of any particular pair be chosen? What is the probability that the pair chosen is Jake up and Meg or Geraldo and Sally?

Answer 1

Step 1

`Probability\text{ of any event = }\frac{number\text{ of required outcomes}}{number\text{ of sample space}}`

Step 2

a) The probability of any particular pair be chosen

`\begin{gathered} =\text{ }(1)/(8)\text{ }*(1)/(7) \\ =\text{ }(1)/(56) \end{gathered}`

b)

the probability that the pair chosen is Jake up and Meg or Geraldo and Sally

`\begin{gathered} =\text{ }(0)/(8)*(1)/(8)\text{ + }(1)/(8)\text{ }*\text{ }(1)/(56) \\ =\text{ }(1)/(56) \end{gathered}`
