Answer:

78%

Step-by-step explanation:

Given the information, we can write:

P(cook) = 52%

P(shop) = 54%

P(cook and shop) = 28%

Now, we need to find P(cook or shop).

We need probability formula for general addition rule, which is:

P(A or B) = P(A) + P(B) - P(A and B)

We can take "cooking" and Event "A" and "shopping" as Event "B".

Thus, we write:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.52 + 0.54 - 0.28

P(A or B) = 0.78

Which is 78%

Hoochie [10]

it would take Janis 14 minutes to complete a package alone

<h3>How to determine the value</h3>

Carol working time = x = 30 minutes

Janis working time = y

x + y = 16 minutes

Let's make 'y' the subject

30 - 16 = y

y= 14 minutes

Thus, it would take Janis 14 minutes to complete a package alone
