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%)
Answer:
45
Step-by-step explanation:
<u>First we want to understand the Base Angles Theorem</u>
The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.
Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.
We can create the equation ∠N + ∠A + ∠G = 180 degrees.
Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into
<em>90 + 2x = 180</em>
We can then solve for x,
<em>90 + 2x - 90 = 180 - 90</em>
<em>2x = 90</em>
<em>2x / 2 = 90 / 2</em>
<em>x = 45 </em>degrees
