A baby cries if and only if she is hungry or tired, or both. Let 𝐻 = the baby is hungry , 𝑇 = the baby is tired ; 𝐶 = the baby is crying Assume: 𝑃 ( 𝐻 ) = ℎ , 𝑃 ( 𝑇 ) = 𝑡 , 0 < ℎ , 𝑡 < 1 and assume that (H) and (T) are independent. Answer the following question: (b) Compute 𝑃 ( 𝐻 ∣ 𝐶 )  

A random bit generator produces keys with the following probabilities: Probability of generating a 0 = 1/4 Probability of generating a 1 = 3/4 Suppose you encrypt a single-bit plaintext (which has an equal probability of being either 0 or 1) using XOR with a key from this generator. You observe that the ciphertext bit is 1. What is the probability that the original plaintext bit was 0? Hint: - Compute the probability for the following table: M = 0, K = 0, C = 0, probability = ? M = 0, K = 1, C = 1, probability = ? M = 1, K = 0, C = 1, probability = ? M = 1, K = 1, C = 0, probability = ? - Then given ciphertext is 1, which scenarios can we rule out immediately? - Finally, calculate the probability that plaintext (M) was 0 given ciphertext is 1 i.e., P(M=0, C=1) / P(C = 1)
