Question 14 options: P(B) = P(Ac & B) + P(A & B) P(Ac & B) = P(B) - P(A & B) P(A or B) = P(A) + P(B) - P(A & B) all of these none of these Question 15 Consider the probability experiment in which two cards are sequentially selected from a standard deck of playing cards. Denote the events the first card is a king and the second a heart by K₁ and H₂, respectively. We have P(K₁) = 4/52 and P(H₂) = 13/52. It was shown that P(K₁ & H₂) = 1/52. Note that K₁ = (K₁ & H₂) or (K₁ & Hc₂) are mutually exclusive (disjoint), then P(K₁) = P(K₁ & H₂) + P(K₁ & Hc₂). The probability the event K₁ & Hc₂ will occur is .

Denote the events the first card is a king and the second a heart by K₁ and H₂, respectively. Recall that for two events A and B, P(A|B) is equal to P(A & B)/P(B) if P(B) ≠ 0 and is equal to zero if P(B) = 0. The probability the first card drawn is a king given the second card is a heart is written as P(K₁|H₂). What is P(K₁|H₂)? Question 16 options: 13/52 4/52 1/52 16/52 none of these

Question 15
Consider the probability experiment in which two cards are sequentially selected from a standard deck of playing cards. Denote the events the first card is a king and the second a heart by K₁ and H₂, respectively. We have P(K₁) = 4/52 and P(H₂) = 13/52. It was shown that P(K₁ & H₂) = 1/52. Note that K₁ = (K₁ & H₂) or (K₁ & Hc₂) are mutually exclusive (disjoint), then P(K₁) = P(K₁ & H₂) + P(K₁ & Hc₂). The probability the event K₁ & Hc₂ will occur is ____.

Question 16
Consider the probability experiment in which two cards are sequentially selected from a standard deck of playing cards. Denote the events the first card is a king and the second a heart by K₁ and H₂, respectively. Recall that for two events A and B, P(A|B) is equal to P(A & B)/P(B) if P(B) ≠ 0 and is equal to zero if P(B) = 0. The probability the first card drawn is a king given the second card is a heart is written as P(K₁|H₂). What is P(K₁|H₂)?
