please dont use excel or other software. plz solve using normal methods

A government space project is conducting research on a certain engineering problem that must be solved before man can fly to moon safely. Three research teams are currently trying three different approaches for solving this problem. The estimate has been that the probability that the respective teams (call them A, B and C) will not succeed are 0.4, 0.6 and 0.8 respectively. Since the objective is to minimize the probability of compound event of failures of these teams, the decision has been taken to assign atmost two top scientists among the three teams in order to lower it as much as possible. The following table gives the estimated probability that the respective teams will fail when 0. 1, 2 additional scientists are added to them. Team A B. 0 0.4 0.6 0.8 10.2 0.4 0.5 2 0.15 0.2 0.3 Number of additional Scientists How should the new scientists be allocated to the teams
