What is the probability of 4 cards being red if all the red faced cards and black faced cards numbered 2-9 are put into a bag and randomly drawn?
The probability of the first card being red is 16 in 32. The probability of the second card being red is 15 in 31. The third is 14 in 30. The fourth is 13 in 29. Multiply these probabilities together and you get 16 x 15 x 14 x 13 in 32 x 31 x 30 x 29, which is equal to 43680 in 863040 or about 0.0506.
What is the probability of selecting a jack or king on a single draw from deck of cards?
That is a rather hard question to answer. It would really depend on how many cards you have in the deck and how many jacks and kings you have Ex: If you had 30 cards and 5 jacks and kings then the probability would be 10/30 or 1/3
What is the probability that a randomly chosen month has 30 days?
there are 4 monthes that has 30 days each year there are 12 monthes each year. so the probabillity for picking a month that has 30 days in it is 4/12
How do you find the odd of picking a green marble 3 yellow 4 blue 6 green and 7 pink marbles?

Two cards are drawn from a deck of cards what is the probability that both cards have a point value of 10?
A deck of cards consists of 52 cards. Each card is available four times. That makes 13 diffent card types. Four different cards are worth 10 points: 10, Jack, Queen, King. That means that 4x4 Cards out of 52 are worth ten. That are about 30% (30/100). Two tens in a row have the expectation of 30%x30% which is about 9%.

What is the probability of drawing a 7 an 8 or a red card out of a 52 card deck of playing cards?
15/26 I think because half the 7 and 8 are red so that's 4+26(red cards) which =30/the 52 possible cards and simplify
A bag of letter tiles contains 5 As 3 Bs and 2 Cs what is the probability of picking ABC in order in three draws from the bag without replacement?
The probability of picking ABC, in that order, from 5 A's, 3 B's, and 2 C's, without replacement, is (5 in 10) times (3 in 9) times (2 in 8), or 30 in 720, or 3 in 72, or 1 in 24.

What is the probability if Three squares are randomly chosen from a chess board such that two of them have one color and the third square has another color is?
There are (64 x 63 x 62)/(3 x 2) possible sets of 3 squares; there are 2 x (32 x 31 x 30)/(3 x 2) sets of 3 the same colour. Of the 41664 possible threesomes, 9920 are identical in colour, a probability of 0.238 Added: This is identical to the probability of picking three odd or three even numbers from a bag containing the first 64 bingo balls! Second add-on: I have amended the original answer which was wrong! The alternative calculation is that after picking one square there are 31 of the remaining 63 which will be of the same colour and if that is so there will be 30 out of 62 to complete the trio. The calculation (simpler!) is thus 31/63 x 30/62 or 930/3906, a probability of 0.238.
