Explanation
A probability of 0.42 is the same as 42% or \(\frac{42}{100}\). The probability of two events occurring is the product of each individual event occurring:

Fastest wat to do it: 1. Express the total probability P(A&B) as P(A) . P(B) 2. List all factors which when multiplied would produce P(A&B) = 0.48 3. Find a conflicting value with 0.58 4. BAM! WE BROKE IT! WE FOUND A CONFLICT! IT'S ANSWER D!

Quantity A: The probability that event E will occur Quantity B: 0.58 • Quantity A is greater. • Quantity B is greater. • Both Quantities are Equal • Cannot be determined
Based on the info, we know that E and F at least both have the probability of 0.42.
Meanwhile, since the maximum of probability is 1, then we can deduce that 0.42=<E<=1.

We can use a Double Matrix to quickly/easily test possible situations.
For example, let's say we have a population of 100 stuffed toys, and some toys have FRECKLES, and some toys have EARS. So, P(event E) = the probability that a randomly selected toy has ears And P(event F) = the probability that a randomly selected toy has freckles And P(E and F) = the probability that a randomly selected toy has ears AND freckles Since we're told that P(E and F) = 0.42, we know that 42 of the 100 toys, have ears AND freckles. We get:
As you can see, there are a lot of different ways we can fill in the remaining three boxes.
One possible case is as follows:
In this case, 52 of the 100 toys have ears. So, P(event E) = 52/100 = 0.52 We get: QUANTITY A: 0.52 QUANTITY B: 0.58 Quantity B is greater
Another possible case is as follows:
In this case, 62 of the 100 toys have ears. So, P(event E) = 62/100 = 0.62 We get: QUANTITY A: 0.62 QUANTITY B: 0.58 Quantity A is greater
