In a two team basketball playoff, the winner is the first team to win m games.(a) counting spereately the number of play-offs requiring m, m+1, and 2m-1 games, show that the total number of different outcomes (sequences of wins and losses by one of the teams) is2[(m-1 / m-1) + (m / m-1) + + (2m-2 / m-1)](b) how many different outcomes are there in a "2 out of 3" playoff, a "3 out of 5", and a "4 out of 7" playoff?

answer is more than one

step-by-step explanation:

the answer is d. 75%

the answers c

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
