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.
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%.
30% or 4/13.
P(7)= 1/30
The probability is (6/14)*(5/13) = 30/182 = 0.1648 approx.

First draw probability of red is 6/10. If first draw is red, then second draw probability of red is 5/9. Multiply the two probabilities to get the overall probability. 6/10 X 5/9 = 30/90 = 1/3
40% chance
The probability with 30 people is 0.7063 approx.
Isometric drawings and shapes are angled to 30 degrees.
When you throw a die, there are six possibilities. The probability of a number from 1 to 6 is 1/6. This is classical probability. Compare this with empirical probability. If you throw a die 100 times and obtain 30 sixes, the probability of obtaining a 6 is 30/100 or 0.3. Empirical probabilities change whereas classical probability doesn't.
The chance it is red is 1/2 The chance it is a jack is 4/52 Now add the two together: 1/2 +4/52 = 30/52 However this double counts the jacks that are red 2/52 so 30/52 - 2/52 = 28/52 Therefore the probability you draw a jack or a red is 7/13
