Astudent wants to check six websites. four of the websites are social and two are school-related. after checking just two sites, she has to leave for school.

what is the approximate probability that she checked a social website first, then a school-related website?

0.042
0.267
0.533

Option B

0.267

Step-by-step explanation:

Probability of checking social-related=4/6

Probability of checking school-related=2/6=1/3

P(first checking social)=4/6

Probability (second school-related)=2/5 (since we have only 5 maximum options having checked the first website)

Therefore, p=4/6*2/5=0.266666667

p≅0.267

The answer is 0.267.

(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
