Please solve; help is appreciated

Chose the graph below that represents the following system of inequality’s

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.

According to the general equation for conditional probability if p(anb)=3/7 and p(b)=7/8 what is p(a i b)
