true or false? If events A and B are independent, then P(AIB) is always equal to...
True/False [1pt each]: Circle T for True or F for False. 1. TIF If the events A and B are disjoint with probabilities P(A) 0.2 and P(B) 0.3, then A and B are independent. 2. T / F If P(A) = 0.6, P(B) 0.4, and P(AIB) = 0.6, then the events A and B are independent. 3. T F The number of heads in 100 tosses of a coin is a discrete random variable. 4 TIF P(AUB) P(A |B) P(B)...
True or false? if it is false please explain Two events A and B are independent if P (AB) P(A)
If events A and B are independent, then P(B|A) is equal to ________. A. P(A) B. P(B) C. P(A∩B) D. P(AUB)
1) True or False: For any two events, A and B, conditional probability is always less than unconditional probability, i.e. P[B|A] < P[B].
2) Suppose A and B are independent events, then() is incorrect. PCAIB) P(A) O P(AnB) P(A)P(B) P(AUB)-P(A)+P(B) 0:(AIB) = P(A)
2) Suppose A and B are independent events, then) is incorrect. A P(AB) P(A) ( PCA n B) = P(A)P(B) P(AIB) = P(A) ⓑ P(A u B)-P(A) + P(8)
1AandBaretwo events suchthat P(A)÷ P(A1B)-큼 and P(AIB)- Show that P(An B)-- 64 (10 marks)
Assume that we have two events, A and B, that are mutually exclusive. Assume further that we know P(A)= 0.30 and P(B)= 0.40. Assume that we have two events, A and Br that are mutually exclusive. Assume further that we know P(A) 0.30 and PCB 0.40 If an amount is zero, enter "0". a. What is P(An B)? b. what is p(AIB? C. Is AIB) equal to A)? Are events A and B dependent or independent? d. A student in...
TRUE OR FALSE _______23. Events are independent when the occurrence of one event has no effect on the probability that another will occur. _______24.The P(x) is always 0 ≤ P(x) ≤ 1. _______25. The mean of the discrete probability distribution for a discrete random variable is called its expected value
5. Let A, B be events. (a) Calculate P(AB') if you are given that A, B are independent and P(A) (b) Calculate P(A) if you are given that P(AIB') P(AIB)
