Answer:
rectangular prism, 6 faces, 8 vertices
D=event that chip selected is defective
d=event that chip selected is NOT defective
Four possible scenarios for the first two selections:
P(DDD)=15/100*14/99*13/98=13/4620
P(DdD)=15/100*85/99*14/98=17/924
P(dDD)=85/100*15/99*14/99=17/924
P(ddD)=85/100*84/99*15/98=17/154
Probability of third selection being defective is the sum of all cases,
P(XXD)=P(DDD)+P(DdD)+P(dDD)+P(ddD)
=3/20
A) set them equal to 180° so it should be 180=5x+10 and x=34 plug it in and VRX=56° and WRV=124°
B represents the fraction of her crop for each store recieves
