Answer:
The required probability is 4/7.
Step-by-step explanation:
The sample space for the experiment is: { BB, BR, RB, RR }
The outcome of the event we require is: { BR, RB }
The probabilities for each outcome is given as:
BB: 3/7 x 2/6 = 1/7
BR: 3/7 x 4/6 = 2/7
RB: 4/7 x 3/6 = 2/7
RR: 4/7 x 3/6 = 2/7
Adding the probabilities we have:
{ BR, RB} = 2/7 + 2/7 = 4/7
That's it!
