Answer:
The expected number of days until the prisoner reaches freedom is 2.8.
Step-by-step explanation:
Door 1: 0.3 probability of being selected. Leads to his cell after two days' travel.
Door 2: 0.5 probability of being selected. Leads to his cell after four days' travel.
Door 3: 0.2 probability of being selected. Leads to his cell after one day of travel.
What is the expected number of days until the prisoner reaches freedom?
We multiply the probability of each door being used by the time that it leads to the cell. So
E = 0.3*2 + 0.5*4 + 0.2*1 = 2.8
The expected number of days until the prisoner reaches freedom is 2.8.

Answer:
Step-by-step explanation:
total sold amount= 1200+1350=2550
profit amount on first radio= 1200-(1200/1.2)=1000
purchase amount of 1st radio= Rs. 1000
total purchased amount= (2550/1.02) = Rs. 2500
purchase amount of second radio= 2500 - 1000 = Rs. 1500
loss % on second radio= ((1500-1350)/1500 ) * 100 = 10%
