Answer:
Expected return for site A = $9.6 million
Expected return for site B = $12.4 million
according to the above results the company should choose SITE B because it has higher Expected return
Step-by-step explanation:
Given;
For site A,
Site A net if successful = $30 million
Success probability = 0.4
Site A loss if not successful= -$4 million
Probability of not successful = 0.6
For site B.
Site B net if successful = $60 million
Success probability = 0.3
Site B loss if not successful= -$8 million
Probability of not successful = 0.7
To estimate the expected return on an event with outcomes X1 and X2 with probabilities p1 and p2
E = X1(p1) + X2(p2)
Substituting for site A
E = 30(0.4) - 4(0.6)
E = $9.6 million
Substituting for site B
E = 60(0.3) - 8(0.7)
E = $12.4 million
Therefore, according to the above results the company should choose site B because it has higher Expected return

Answer:
0.33 ft
Step-by-step explanation:
From the diagram, triangle ACE is similar to triangle BCD.
Therefore,
Let the Length of the Ladder, L
Using Pythagoras theorem
To find the least value, we have to equate the derivative of L to 0.
Therefore:
b³-1080=0
b³=1080
b=10.26
The minimum length of the ladder is:
=0.33 ft
