The combinations (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) lead to a sum of 7. There are 6 such combinations out of 36 possible outcomes, hence the probability is 1/6.
There are 13 hearts and 4 kings in a deck, totaling 17 cards. However, one king overlaps with hearts, making it 13 + 3 = 16 distinct cards. The probability is 17/52.
Binomial distribution gives the probability as C(4,2)(1/2)^4 = 6*(1/16) = 3/8.
The expected value is calculated as (1+2+3+4+5+6)/6 = 3.5.
The binomial distribution is for scenarios with two outcomes, like success or failure, with fixed trials and constant probability. Hence, Binomial distribution is correct.
There are 4 aces in a deck of 52 cards. Therefore, the probability is 1/13.
Mutually exclusive events cannot occur simultaneously, hence their joint probability is 0.
A standard deck of cards has 26 red cards. The probability of drawing a red card is 1/2.
For independent events, P(A and B) = P(A) * P(B) = 0.4 * 0.5 = 0.2.
The standard deviation measures the spread or variability of a probability distribution. Hence, the correct answer is Standard deviation.
