Question

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?

0.042
0.267
0.533
0.667

Answer 1

P(first social then school) = (4/6) * (2/5) = 8/30 = 4/15 ≈ 0.267

So the correct choice is 0.267.
