The first time the band leader selects one member, the probability that either you or your brother gets selected would be 2 out of 80 or in fraction 2/80.
Now, once one of you gets chosen, for the next selection, there are only 79 members left and the probability that the remaining one (between you and your brother) gets selected after is 1/79.
So, if you are both to be selected, the combined probability for that to happen will be (2/80)(1/79) = 1/3160.
Therefore, the answer is 1/3160<span>.</span>
Y = 2x + 1
y = 2x - 1
so the 1st one has a y int of 1 and the second one has a y int of -1...so the original line will shift down 2 units
I believe it is Infinitely Many Solutions
