Pearl is preparing a proof for the converse of the triangle proportionality theorem using the image above. she knows that ad over ab equals ae over ac: statement reason 1 ad over ab equals ae over ac given 2 ∡a ≅ ∡a reflexive property 3 δdae ~ δbac side-angle-side (sas) similarity postulate 4 ∡ada ≅ ∡abc corresponding angles of similar triangles are congruent 5 de || bc converse of corresponding angles postulate in which step is her first mistake?

∠A ≅ ∠A; reflexive property

Step-by-step explanation:

1. It is not a fair game.

2. The game is not fair because the probability of winning and the probability of losing are not equal.  In a fair game, the probability of winning is equal to the probability of losing.  In this game, the probability of losing is 0.81 or 81%, while the probability of winning is 19% (100 - 81).

Step-by-step explanation:

Cost of playing the game one time = $3

Total number of bills in the box = 124 (100+20+3+1)

Chance of losing is represented by 100 of $1 bills = 100/124 = 0.81 or 81%

Chances of losing are represented by 20 of $5 bills, 3 of $20 bills, and 1 $100 bill = 0.19 or 19% (20/124 + 3/124 + 1/124).
