Answer:
Step-by-step explanation:
If there are twelve contestants, the number of ways in which they can select the first and second turn can be calculated using the rule of multiplication as:
<u> 12 </u>*<u> 11 </u>= 132
1st turn 2nd turn
Because, they are going to have 12 contestants for the first turn and then they are going to have 11 contestants for the second.
On the other hand, 1 of these options is that you go first and your friend goes second, so the probability that this happens is equal to:
3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
Answer:
x= 1
