A bag contains 10 marbles: 4 are green, 4 are red, and 2 are blue. Ivanna chooses a marble at random, an without putting it back, chooses another one at random. What is the probability that the first marble is blue and the second is green ? Write your answer as a fraction in simplest form.

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
