This is a probability case of statistics using the addition rule
P(A or B) = P(A) + P(B) - P(A and B).
The output can happen at the same time, for that reason it is not mutually exclusive. The output can be an ace and a black card.
first case: how many ace's we got=4 over the number of total cards=52
second case: how many black cards=26 over the total number of cards=52
BOTH cases: they can be just 2 cards that can be aces AND black.
(4/52)+(26/52)-(2/52)= 7/13=.538461538462= .5385
The probability is 0.
The probability is 1. It must be "a red or black card".
The probability of choosing a red or black card from a standard deck of 52 cards is 52 in 52, or 1 in 1. In other words, it will happen no matter what.
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.
The probability is 16/52 = 4/13
The probability is 0.
The probability is 1. It must be "a red or black card".
The probability of choosing a red or black card from a standard deck of 52 cards is 52 in 52, or 1 in 1. In other words, it will happen no matter what.
The probability is 0.25
The probability of drawing a red or black card from a standard deck of playing cards is 1 (a certainty). This is because these are the only options available.
The probability is 16/52 = 4/13
The probability of getting two pairs in a standard deck of playing cards is higher than the probability of getting three of a kind.
The probability of drawing three black cards one at a time with replacement from a standard deck of 52 cards is 1/3x1/2x26/52, which is 0.833.
A card is drawn from a standard deck of playing cards. what is the probability that a spade and a heart is selected?
The answer depends on how many cards are drawn. If you draw 40 cards, the probability is 0. The probability of not drawing a spade in a random draw of one card from a standard deck is 39/52 = 3/4.
The probability is 1/13 of drawing a king in one draw from a standard deck with no jokers.
There are two black 7's and two red queen's in a standard deck of playing cards. The probability of drawing a black 7 is 2 in 52, or 1 in 26, or about 0.038. The probability of drawing a red queen from the remaining 51 cards is 2 in 51, or about 0.039. The probability, then, or drawing a black 7 followed by a red queen is (2 in 52) times (2 in 51), which is 4 in 2652, or 2 in 1326, or about 0.00151.
