What is the probability of drawing a black card and a 7?
To calculate the probability of drawing a black card and a 7 from a standard deck of 52 cards, we first determine the total number of black cards and the number of 7s in the deck. There are 26 black cards (13 spades and 13 clubs) and 4 sevens in the deck. The probability of drawing a black card and a 7 is calculated by multiplying the probability of drawing a black card (26/52) by the probability of drawing a 7 (4/52), resulting in a probability of (26/52) * (4/52) = 1/26 or approximately 0.0385.
If A bag contains 3 orange 5 black and 2 white marbles Two marbles are drawn but the first marble is not replaced Find P white then black?
Bag with 10 marbles: 3 orange, 5 black, 2 white.Rephrasing the question.If a marble is drawn from the bag, then returned to the bag, and a second marbleis drawn, what is the probability that the first marble turns out white and the secondmarble black ?The probability for a marble to come out white from the bag is:P(W) = 2/10 = 1/5The probability for a marble to come out black from the bag is:P(B) = 5/10 = 1/2The probability for a marble to come out white, put back in the bag and then take again a marble for a second time and turns out to be black is:P(B2|W1) = (1/5)∙(1/2) = 1/10 = 0.10 = 10 %
A bag contains green and yellow tiles You pick 2 tiles without replacing the first one The probability that the first tile is yellow is 35 The probability of drawing 2 yellow tiles is 1235?
What is the probability that the second tile you pick is yellow? (didnt have enough space to finish the question)
There were 6 purple socks and 4 orange socks in a drawer Zucky picked one sock without looking and then another without looking replacing the first what is the probability that he picked 2 purple?
Probability of picking purple sock first time is 6/10 or 3/5, second time, probability is 5/9. Thus 3/5 * 5/9 = 15/45 which cancels to 1/3
What is the probability of drawing 3 black cards (spades or clubs) from a standard 52-card deck?
The probability of drawing three black cards from a standard pack depends on:whether the cards are drawn at random,whether or not the drawn cards are replaced before the next card is drawn,whether the probability that is required is that three black cards are drawn after however many draws, or that three black cards are drawn in a sequence at some stage - but not necessarily the first three, or that the first three cards cards that are drawn are black.There is no information on any of these and so it is not possible to be certain about the answer.The probability of drawing three black cards, in three random draws - without replacement - from a standard deck, is 0.1176 approx.
If a drawer contains 10 black socks 12 gray socks and 7 white socks what is the probability the first 2 socks will be black?
(10/29)(9/28)= 0.110837438 or about 11.1%

A pack of 52 playing cards of shuffled and one card is dealt from the top of the pack What is the probability that is a black card?
There are 52 cards of which 26 (a half) are black. So he probability that the first card is black is 26/52= 1/2
Which shows the probability of choosing 2 white socks from a drawer having 6 white 3 black socks 3 brown socks and 8 gray socks?
I assume you are selecting two socks (one at a time) from the drawer to wear (for example). There are 6 white + 3 black + 3 brown + 8 gray = 20 socks in all So the probability that the first sock chosen to be white is 6/20 since there are 6 socks and 20 socks in total. 6/20 reduces down to 3/10. The probability that the second sock chosen is also white is 5/19 since there are now only 5 white socks left to be chosen and 19 socks in total (since one sock has been taken out). Thus the probability of both socks being white is: probability = 3/10 x 5/19 = 3/38
A bag contains green and yellow tiles You pick 2 tiles without replacing the first one The probability that the first tile is yellow is 35 The probability of drawing 2 yellow tiles is 1235?

8 identical balls are placed at random in three bags. what is the probability that the first bag will contain 3 balls?
The probability that it contains exactly 3 balls is 6/45 = 0.133... recurring.
How can I remove a cabinet drawer?
To remove a cabinet drawer, first, open the drawer fully. Look for release tabs or screws on the drawer slides. Press the release tabs or unscrew the screws to detach the drawer from the slides. Lift the drawer up and out to remove it completely.
What is the probability that the first card is an an ace or the second card is black?
The answer depends on whether or not the first card is replaced before the second is drawn.
Who was the first drawer?

There were 6 purple socks and 4 orange socks in a drawer Zucky picked one sock without looking and then another without looking replacing the first what is the probability that he picked 2 purple?
Probability of picking purple sock first time is 6/10 or 3/5, second time, probability is 5/9. Thus 3/5 * 5/9 = 15/45 which cancels to 1/3
