Thanks, will rate lifesaver! Please show and explain all work! Solution Let ij mean the probability of i the first week and j the second week ans =07+16+25+34+43+52+61+70 ij=(Probability of i the first week)(probability of j the second week) since independent ij=(1/2^(i+1))(1/2^(j+1))=1/2^(i+j+2) ans=8/2^(7+2)=8/2^9)=1/2^6.
