Walt has a box of 80 postage stamps. the box contains 16 stamps featuring the bald eagle and 40 stamps featuring the stars and stripes.

if walt randomly chooses a stamp to paste on an envelope, what is the probability that the stamp features the bald eagle or the stars and stripes?
a) 0.30
b) 0.50
c) 0.70

d) 0.80

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α. part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part b suppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
