(i) Find the expected number of white balls drawn. (ii) If each white ball drawn carries a reward of Rs. 4 and each red ball Rs. 6, find the expected reward of the draw. , 2. A contractor spends Rs. 3,000 to prepare for a bid on a construction project which, after deducting manufacturing expenses and the cost of bidding, will yield a profit of Rs. 25,000 if the bid is won. If the chance of winning the bid is ten per cent, compute his expected profit and state the likely decision on whether to bid or not to bid. , This mathematics video is very useful to all #ug, #pg students of #datascience, #ai, #machinelanguage, #maths , #science , #computerscience , #statistic , #msc , #bsc, #mcom , #bcom , #bca , #mca , #bba , #mba , #engineering , #be , #btech , #me , #mtech , #appliedmathematics , all #competitiveexams like #gate , #net , #selt , #trb , #pgtrb , etc. #businessmathematics , #bcommathematics , #bcomstatistics , #mcommathematics , #mcomstatistics , #bscstatistics , #mscstatistics , #mscmathematics , #bscmathematics , #mbamathematics , #mbastatistics , #engineeringstatistics , #engineeringmathematics , #maths #math #engineeringmaths #engineeringmathematics #cse, #eee ,#ece ,#mechanical, #biotech, #civilengineering , #electricalengineering , #electronicsengineeering , #biomedical , #aeronauticalengineering , #aerospaceengineering , #geotech, #architecturalengineering , #nanotechnology , #automativeengineering , #structuralengineering , #mechatronicsengineering , #roboticsengineering , #competitiveexams , #computerscienceengineering , #artificialintelligence , #datascience , contains systematic procedures to understand by the reader without any guidance. it covers definition with proper examples. each topic includes different types of problems with solutions. for high school & higher secondary maths, please refer to the channel https://www.youtube.com/channel/uc2ifm8cxotcznzvlscdlnhq/ channel name: i am weak in maths please subscribe, like & share🙏 , please share this video to your friends & needy 🙏
