Alex, Lizzie, Winnie, and Greg decided to randomly switch their four lunch boxes. If they each choose one of the four boxes at r

Well if three of them end up with the same lunch box and there are only 4 total lunch boxes, then that means all of them would get their original lunchbox.

For that to happen there is a 1/4 chance for each person to correctly pick their lunchboxes.

So it’s 1/4*1/4*1/4*1/4 and that equals to 1/256.

So there is a 1/256 chance that they will end up with their original lunch box.

Hope this helps!

In a standard deck of cards there 52 cards of which 26 are black and 26 are red. Additionally, there are 4 suits, hearts, clubs,

stich3 [128]

Using probability concepts, it is found that P(S and D) = 0.1275.

-----------------------

A probability is the <u>number of desired outcomes divided by the number of desired outcomes</u>.
In a standard deck, there are 52 cards.
Of those, 13 are spades, and 13 are diamond.

The probability of selecting a spade with the first card is 13/52. Then, there is a 13/51 probability of selecting a diamond with the second. The same is valid for diamond then space, which means that the probability is multiplied by 2. Thus, the desired probability is:

$P(S \cap D) = 2 \times \frac{13}{52} \times \frac{13}{51} = \frac{2\times 13 \times 13}{52 \times 51} = 0.1275$

Thus, P(S and D) = 0.1275.
