Aproper unbiased coin was tossed 10 times for 3 trials, giving tthhthtthh, , and ththhthtth (t = tails; h = heads). what is the difference between the theoretical and experimental probabilities of getting heads?

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

y-3=-3/2(x+4)

ur very much welcome
