Probability a gets a head = 1/2
.. .. .. b .. .. ... .. = P(a gets tail) * 1/2 = 1/2 * 1/2 = 1/4
.. ... . .. c .. .. .. .. . = P(and and b gets tail) * 1/2 = 1/4 * 1/2 = 1/8

Answer:
Step-by-step explanation:
<u>27.</u> the sum of 2 complementary angles=90
8x-17+5x-10=90
13x=90+27
13x=117 <u>x=9 </u>
<u>28. </u> the sum of supplementary angles=180
17x-12+3x-48=180
20x=180+60
20x=240
<u>x=120</u>
