Wendy throws a dart at this square-shaped target:

Part A: Is the probability of hitting the black circle inside the target closer to 0 or 1? Explain your answer and show your work. )

Part B: Is the probability of hitting the white portion of the target closer to 0 or 1? Explain your answer and show your work. [ pl help I have one day to do this and its worth ALOT OF POINTS HEL ps. don't forget to give me how you solved it . thanks

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
