The probability that India wins against Australia but not against Pakistan is 0.4-0.3=0.1. The probability that they win against Pakistan but not against Australia is 0.7-0.3=0.4. The probability that they win at least one game is the sum of the probabilities that they win only against Australia, only against Pakistan and against both, therefore it equals 0.4+0.1+0.3=0.8.
