Solution

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}
