Answer:
0.854 (85.4%)
Step-by-step explanation:
Since each bet is independent from others , then for X=gambler’s winnings when she quits
P(X>0) = probability to win in the first bet + probability of losing in the first bet * probability of wining at least one of the 2 additional bets
= 18/38 + (1-18/38) * [18/38*(1-18/38)+(1-18/38)*18/38+18/38*18/38 ] =0.854 (85.4%)
10x = 15y + 5 (by the vertical angle theorem).
8x + 1 + 7y + 10x = 180 ( by triangle sum theorem)
18x + 7y = 179 .............(1)
from first equation :-
10x - 15y = 5.................(2)
Multiply (1) by 10 and (2) by -18:-
180x + 70y = 1790
-180x + 270y = -90
Adding :-
340y = 1700
y = 5
and from first equation
10x = 15(5) + 5 = 80
x = 8
Answer x=8, y = 5.
