Assume when adults with smartphones are randomly selected, 53% meetings or classes10 adult smartphone users are randomly selected find the probability that at least 4 of them use their smartphones in meetings or classes

answer:  

123455421

step-by-step explanation: easy

(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

the answer is 3/2 and for decimal: 1.5
