Can you Specify the Question?
Answer:
53.13°
Step-by-step explanation:
Using Sine rule
b / Sin B = a / Sin A
5/ Sin90 = 4 /Sin A
5/1 = 4 /SinA
Sin A = 4/5
A = arc sin(0.8)
A = 53.13010
A = 53.13 °
<span>Expected value is the sum of the probability of each even times the outcome of the event.
So she wins $10 with probability 2/8, $3 with probability 1/8, $0 with probability 3/8, and loses $3 with probability 2/8.
So,
E = 10(2/8) + 3(1/8) + 0(3/8) - 3(2/8)
=5/4 + 3/8 - 3/4
=7/4
