A student 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?

Answer: 0.267

Step-by-step explanation:

The probability when she checks social website first = 4/6

Now, she is left with 5 webistes out of which two are school-related so probability = 2/5

So, the probability when she checks social webiste first and school related website later = 4/6 x 2/5

Probability = 0.267
