Find the probability of choosing a letter other than the letter E from a bag that contains the fifteen letters of the name KARL WEIERSTRASS. Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

see below

Step-by-step explanation:

angle JP = (180 - 32 - 90) + (180 - 22 - 90)

              = 58 + 68

              = 126°

angle JKP = (360 - JMP - JLP - LNP)/2

                 = 360 - (180 - 32 - 90) - 126 - (180 - 22 - 90)

                                                     2

                  = 360 - 58 - 126 - 68

                                    2

                  = 54°

MP = 7

KN = 10

JP = 11 / cos(32)

    = 13

PL = 17 / cos(22)

    = 18.3
