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

Answer 1

Answer:

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

Answer 2

Answer:

The answer is 0.267.
