Do moles live in their tunnels or do they have a sort of underground den or nest that they return to after a hard night of digging?

Do moles dig alone or do they travel around in herds?

Why do moles tunnel around, popping up into the middle of your lawn every now and then?

How many baby moles does a mother mole give birth to, and how long is a mole's gestation period?

There are four balls, each with a distinct integer label, in a bag. It is known that the product of the
integers on the labels is 24. If a ball is picked at random, the probability that the label is an even natural
number is:
(1) ¼ (2) ¾ (3) ½ (4) None of these

solution:
-----------
If there are four balls in a bag each with an integer label and the product = 24, then the labels have to be 1, 2, 3,4 or (-1, -2, -3, -4) or (1, 2, -3, -4) or (1, -2, -3, 4) and so on. As the product of the 4 integers is positive either two
or four of the integers have to be positive. Taking conditional probabilities, the answer obtained is none of the
choices (1) to (3).


Question:
--------------
i dont understand how they solved it. whats the meaning with "Taking conditional probabilities, ......"

how this can help to achieve the solution ?

can u help ?

thanks

Sometimes when someone takes a photo, it is noticed that people's eyes show a red spot. It's not happen all the time, What are the reasons when happens? and why other mammals' eyes (like cats, cows, horses...) do not show that characteristic? In fact, they show bright eyes in photos.

For every thing there should be an end or decline to reach a ground state. But the universe is going on expanding. What is the end for it? The existing energy in the universe will be diluted and after some times, vacuums of energy will be created in the universe (energy can neither be created nor be destroyed). If any imaginary end exists, what will be there behind it?

Please do not use social or political separations to define the continental boundaries in answering this question.It is a geographic issue.Both are one land mass wholly connected, and are on the same tectonic plate.Why then are we told 7 continents when there are 6.And why does academia regard Europe and Asia as seperate continents when geographically they are clearly one continent.
