Answer: Expected profit for first and second project are $158000 and $185000 respectively.
Step-by-step explanation:
Since we have given that
First project :
a profit of $170,000 with a probability of 0.7 or a profit of $130,000 with a probability of 0.3
0.7 $170000
0.3 $130000
So, Expected profit would be
![E[x]=\sum xp(x)=0.7\times 170000+0.3\times 130000=\$158000](https://tex.z-dn.net/?f=E%5Bx%5D%3D%5Csum%20xp%28x%29%3D0.7%5Ctimes%20170000%2B0.3%5Ctimes%20130000%3D%5C%24158000)
Second project:
a profit of $230,000 with a probability of 0.7 or a profit of$80,000 with a probability of 0.3.
0.7 $230000
0.3 $80000
So, Expected profit would be
![E[x]=\sum xp(x)=0.7\times 230000+0.3\times 80000=\$185000](https://tex.z-dn.net/?f=E%5Bx%5D%3D%5Csum%20xp%28x%29%3D0.7%5Ctimes%20230000%2B0.3%5Ctimes%2080000%3D%5C%24185000)
Hence, expected profit for first and second project are $158000 and $185000 respectively.
