Since there are 4 matches to be played.India can get a maximum of 8 points(2 points in each match).
Probability of getting exactly 7 points = P(Getting 2 points each of 3 matches and getting 1 point in one match)
=$\binom{4}{3}$ (0.5)3 (0.05)1 =0.025
Probability of getting exactly 8 points =P(Getting 2 points in each of 4 matches)
=$\binom{4}{4}$ (0.5)4 (0.05)0=0.0625
P(india gets at least 7 points) =P(Getting exactly 7 points) + P(Probability of getting Exactly 8 points)
= 0.025 + 0.0625
=0.0875
