d. (2/3)^10 + 8/3*(2/3)^9

We have two chances to win the world cup. Either India can win all 10matches or Win 7 out of 8 group matches + win the semi final and final matches.

Case 1:

To win all 10, probability is (2/3)^10.

Case 2:

Probability of winning 7mathces out of 8= (2/3)^7 and

Probability of Loosing the 1 match= 1/3.

This process can occur in 8 ways. probability= 8*((2/3)^7 * 1/3)

To win semi final and final match probability is (2/3)^2

Total probability=8*((2/3)^7 * 1/3) * (2/3)^2 = 8/3 * (2/3)^9.


So total probability, Case1+Case 2= (2/3)^10 + 8/3 * (2/3)^9
