Afair coin is flipped twice. what is the probability of showing heads on both flips

It's important to understand that the two coin tosses are called independent events because the outcome of the first coin toss does not affect the outcome of the second coin toss. To find the probability of independent events, we first find the probability of each event and then multiply the probabilities together.

step-by-step explanation:

(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
