At one point, she believed GMAT wasn’t for her. After scoring 595, self-doubt crept in and she questioned her potential. But instead of quitting, she made the right strategic changes. The result? A remarkable comeback to 695. Check out how Saakshi did it.

Not Sure about the fastest way to do this. But here it goes:
We take into cosndieration all possibilities from 1 par to all 4 pars.
1) Probability of Making 1 Par and missing the other is 0.3 x 0.7 x 0.7 x 0.7 i.e 0.1029 which can be arranged in 4 ways (4 x 0.1029).
2) Probability of Making 2 Pars and missing the other is 0.3 x 0.3 x 0.7 x 0.7 i.e 0.0041 which can be arranged in 6 ways (6 x 0.0041).
3) Probability of Making 3 Pars and missing the other is 0.3 x 0.3 x 0.3 x 0.7 i.e 0.0189 which can be arranged in 4 ways (4 x 0.0189).
4) Probability of Making 1 Par and missing the other is 0.3 x 0.3 x 0.3 x 0.3 i.e 0.0081 which can be arranged in 1 way (1 x 0.081).
The total comes out to 0.7599. Hence, the correct option is D.
I believe the faster method is to do 1 - zero successes but I am still getting better at it so the long way above.

Probability(making or better than 3 par ) = 0.3
Then, the probability (NOT making a 3 par) = 1-0.3 = 0.7
The golf course has exactly 4 par 3 holes.
probability that Matthew will make par or better on at least one of the par-3 holes?
= 1 - {probability (NOT making a 3 par)}^4
= 1 - (0.7)^4
= 1 - 0.2401
= 0.7599
Option D
