Casey finds that when asked for their email address, 15 of her customers will share their address with her. to simulate the behavior of the next 4 customers, she writes the numbers 1, 2, 3, 4, and 5 on cards and mixes them up. she then picks 4 cards, records the results, and puts the cards back.. she repeats this experiment for a total of 20 trials. the results are shown in the table. here, she let 1 represent someone sharing an email address and 2, 3, 4, and 5 represent someone not sharing an email address. 4121 1223 4233 3344 2434 4241 5415 3421 5214 2234 4211 1432 5532 4114 4325 4454 4523 4432 3423 1352 using this simulation, what is the probability that, out of the next 4 customers, fewer than 2 will share their email address? enter your answer, as a fraction in simplified form, in the box.

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 bsuppose 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 cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
