Let ##X## be the event that the first draw is a picture card Let ##Y## by the event that the second is a picture card Then the probability that at least one of the cards is a picture card is the probability of ##X## union ##Y## and has the formula Equation 1 ## P\left(X \cup Y \right) = P...

Hi everyone, I am struggling to understand the difference between FMESH and MESH. FMESH is used to create a mesh superimposed with the geometry but...what does MESH? Is it only involved in weight-window generation and not needed for mesh tallies? Thanks in advance for the clarification.

There are 3 cases of getting 2 as smallest values: (1) Taking one card (n = 1) → Probability = 1/4 (2) Taking two cards (n = 2) → Probability = 1/4 x 2/3 x 2! = 1/3 (3) Taking three cards (n = 3) → Probability = 1/4 x 1/3 x 1/2 x 3! = 1/4 Total probability = 1/4 + 1/3 + 1/4 = 5/6 But the...

Hi PF! I am wondering the differences between the discrete and continuous case for expected value of minimum of 3 integers uniformly distributed from 1 to 13 vs 3 reals from 1 to 13. The real case is direct: ##F = ((x-1)/12)^3 \implies f = 3(x-1)/12)^2## for CDF ##F## and PDF ##f##. Thus the...

The answer is 33 (based on the answer key). At first, I thought Paul can just take all the 100 cards on 1st draw but since the answer is 33, obviously this thought is wrong. So I assume that the rule (2n + 2) must always be satisfied for each turn and all the cards must be taken (no card...

Not really a homework question. I was reading a book on card tricks and it said that it's almost certain that in a shuffled deck of cards, there will be at least two consecutive cards of the same value. I just wanted to know the actual probability of that. So, here's my question: in a standard...

A quick translation of the question: We have a deck of 40 cards, containing four suits (hearts, diamonds, spades, clubs), in which each suit has an ace, a queen, a jack, a king and six number cards (2 to 7). From the deck, six cards are distributed randomly and successively to a player who picks...

Here is my work so far: 52-13=39 There are 39 decks of cards left since the spades were removed. a) Then there 13 hearts therefore, (13/39 ) * (13/39 ) that would be two hearts but I am not sure what to do next. But I am sure that it would be 39 cards and 13 hearts on top (maybe) cus it is...

Say you have a computer (desktop or laptop), and you have, say, 8GB total of RAM. There are two options to get a total of 8GB: 1. Use two 4GB cards. 2. Use one 8GB card. The mechanic who services our desktop says that using two RAM cards is not equivalent to using one single card. He says...

I understand that the odds of drawing one of the unique cards in the first 7 is expressed as 29c6 / 30c7 where NcK is "N choose K" or Binomial[N,K] in Mathematica. Am I correct in using the following to answer my original question? Let q be the first card of interest and q' be the second...

There are 8 cards with number 10 on them, 5 cards with number 100 on them and 2 cards with number 500 on them. How many distinct sums are possible using from 1 to all of the 15 cards?Answer given is 143. But my logic is for any sum, at least 2 numbers are needed. So, there are $\binom{15} {2}...

For example, I don't understand slide 4, line 4 of the link below. I know that the first three numbers are the cell number, material number and density of water. But what do the next 6 numbers mean (2, -1, 4, -3, 5, -6)? Similarly on line 8, what do -0.001293 (101, -102, -100) mean? Thank you...

20 children share some cards equally. When another child joins them, they each get 2 fewer cards. How many cards are they sharing altogether? My answer: children = ch cards = cd => cd/ch but when another child joins them, they get 2 fewer cards. So, ch = cds - 2. then I did cd/20(cds - 2)...

Where I live, using a debit card when paying is the norm pretty much all around, and using cash is quite rare. I've heard that in the US using a card isn't that customary? And if you do you need to sign in addition to entering the PIN? Are establishments where cash is all they'll accept common?
