Answer:

m∠1 = mCD = 40°
m∠2 = 1/2(mAB) = 1/2*30° = 15°
m∠3 = 1/2(mED) = 1/2*50° = 25°
m∠4 = 1/2(mAB + mDE) = 1/2(30°+50°) = 40°
m∠6 = m∠OEG - m∠DEG = 90° - 1/2(mDE) = 90° - 25° = 65°
m∠7 = 1/2(mCD + mDE) = 1/2(40°+50°) = 45°
m∠8 = 1/2(mCD + mDE - mAB) = 1/2(40° + 50° - 30°) = 30°
m∠10 = 1/2mAE = 1/2(180° - mDE) = 1/2(180° - 50°) = 65°

Answer:

42 cents

Step-by-step explanation:

Data provided in the question:

Random variable i.e gain with values 3,2,1,-1.

Now,

The corresponding probabilities will be as follows:

$P(3)=(\frac 16)^{3}$

$P(2)=3\times(\frac 16)^{3}$

$P(1)=3\times(\frac 16)^{3}$

$P(-1)=1-7(\frac 13)^{3}$

Expected gain = $3\times(\frac 16)^{3}+2\times3\times(\frac 16)^{3}+1\times3\times(\frac 16)^{3}-1\times\left(1-7\times(\frac 13)^{3}\right)$

Expected gain = $(\frac 13)^{3}[3+6+3-(0.7407)]$

$=(\frac 16)^{3}[11.2593]=0.4170$

≈ 42 cents
