Question 1058646
It is 1- probability she scores 1 or 0.
probability for 0 is 0.7^15=0.0047
probability for 1 is 15*0.7^14*0.3=0.0305; the 15 comes from 15C1, or that there are 15 possible ways she could score 1 field goal.
They add to 0.0352
1-0.0352=0.9648 or 0.965.
Given that the expected value is 4.5, and the sd is about 1.7, this is a reasonable answer.
