The probability of getting a diamond and a black seven is zero. Diamonds are red.
There are 13 diamonds in a 52-card deck so the probability to get a diamond is 13/52=1/4=0.25
The probability is 1/4
The probability of getting the queen of hearts is 1 in 52, or about 0.01923. The probability of getting any queen is 4 in 52, or about 0.07692. The probability of getting any heart is 13 in 52, or exactly 0.25.
If there is 3 blue 2 red and 4 green. What is the probability of getting green?
The probability of getting a diamond and a black seven is zero. Diamonds are red.
The probability of getting a particular suit (hearts, spades, diamonds, clubs) is 1 in 4. The probability of getting a card less than 8 (2, 3, 4, 5, 6, 7) is 6 in 13. The probability, then, of getting a particular suit less than 8 is (1 in 4) times (6 in 13) or 6 in 52 or 3 in 26.

The "or" in the statement is addition; so even with one coin the probability of getting a head or a tail when spinning it is 1, and since the probability can never be greater than 1, the answer is 1. Correct. I suspect the questioner means something different. Probability of getting H & H = 1/2x1/2 = 1/4 Probability of getting H & T = 1/2 x 1/2 = 1/4 Probability of getting T & H = 1/2 x 1/2 = 1/4 Probability of getting T & T = 1/2 x 1/2 = 1/4 So probability of getting just 1 head = 1/4 +1/4 = 1/2 Probability of getting 2 heads = 1/4 So probability of getting 1 or 2 heads = 1/2 + 1/4 = 3/4 Probability of not getting a head = 1/4 Similarly for switching heads and tails.
The probability is 1/4
The probability of getting the queen of hearts is 1 in 52, or about 0.01923. The probability of getting any queen is 4 in 52, or about 0.07692. The probability of getting any heart is 13 in 52, or exactly 0.25.
If there is 3 blue 2 red and 4 green. What is the probability of getting green?
The answer depends on how many cards are in the hand.
The probability of a club is 1/4 and the probability of a diamond is 1/4 so since they are mutually exclusive you just add them and the total probability is 1/2 Of course there are 4 suits, and clubs and diamonds are 2 of the 4 so we could have just said 1/2.
The probability is 1 out of 5
