Question 1002984
I don't know what passing is.  I will assume 70%.
The 5 possible answers appears not to be relevant, since she has a 75% chance of answering each question correctly.
She has to get 7 or more correct.  
10C7(0.75)^7(0.25)^3=0.2503
10C8(0.75)^8(0.25)^2=0.2816
10C9(0.75)^9(0.25)=0.1877
0.75^10=0.0563
P=0.7759
