The probability a randomly selected household owns corporate stock is 0.54. The probability a randomly selected household has no Internet access is 0.3. Assume whether a randomly selected household owns corporate stock is independent of whether the household has no Internet access. What is the probability a randomly selected household has no Internet access given the household owns corporate stock

30% probability a randomly selected household has no Internet access given the household owns corporate stock

Step-by-step explanation:

I am going to say that we have two events.

Event A: Owning corporate stock. So P(A) = 0.54.

Event B: Having no internet access. So P(B) = 0.3.

Since they are independent events, we can apply the conditional probability formula, which is:

In which

P(B|A) is the probabilitty of event B happening given that A happened. We want to find this.

is the probability of both events happening.

Since they are independent

So

30% probability a randomly selected household has no Internet access given the household owns corporate stock

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
