... one of the two courses. Thus we can use what we know about complements to find the probability of Alex failing both courses. It will be 1 - 0.80 = 0.20. d. The probability that Alex will pass exactly one course is the probability that Alex will pass only algebra or Alex will pass only history. Since ...

... Intuitively, we can think of a probabilistic Turing machine as an ordinary deterministic TM, except that at certain points in the computation it can flip a fair coin and make a binary decision based on the outcome. The probability of acceptance is the probability that its computation path, directed b ...

And suppose that the mean height for policewomen is 65 inches with a standard deviation of 2.5 inches. If heights of policemen and policewomen are Normally distributed, find the probability that a random ...

... If P (B|A) = P (B), i.e., the occurrence of the event A does not affect the probability of the event B, then we say that the two events A and B are independent. In this case the above formula gives P (A ∩ B) = P (A) · P (B). This formula is known as the ”multiplication rule of probabilities”. If two ...

... Discrete: If the possible values change by steps or jumps. Example: Suppose we flip a coin 5 times and count the number of tails. The number of tails could be 0, 1, 2, 3, 4 or 5. Therefore, it can be any integer value between (and including) 0 and 5. However, it could not be any number between 0 and ...

Since we replace the letter we draw, each drawing of a letter is equally probable and so we say the events are independent. If two things are independent, the ...

No, because there are 21 men with 0 activities. (c) (6 points) We want to check if the events “female” and “5-7 activities” ...
