Homework Answers
P(at least one head) =1-P(no head in n toss) =1-(1/2)n >=0.99
(1/2)n <=0.01
taking log on both sides
n >=ln(0.01)/ln(0.05)
n>=6.64
n.=7

Suppose you toss an unfair coin 8 times independently. The probability ofgetting a head is 0.3. Denote the outcome to be 1 if you get a head and 0 if a tail. (i) Write down the sample space Ω. (ii) What is the probability of the event that you get a head or a tail at least once? (iii) If you get eight same toss's you will get x dollars, otherwise you will lose 1 dollar. On average, how large...

Suppose we toss a weighted coin, for which the probability of getting a head (H) is 60% i) If we toss this coin 3 times, then the probability of getting exactly two heads (to two decimal places) is Number ii) If we toss this coin 6 times, then the probability of getting exactly four heads (to two decimal places) is Number CI iii) if we toss this coin 8 times, then the probability of getting 6 or more heads (to...

Suppose that the probability of getting a head on the ith toss of an ever-changing coin is f(i). How would you efficiently compute the probability of getting exactly k heads in n tosses?

Suppose that I toss a fair coin 100 times. Write 'p-hat' for the proportion of Heads in the 100 tosses. What is the approximate probability that p-hat is greater than 0.6? 0.460 0.023 0.540 We can't do the problem because we don't know the probability that the coin lands Heads uppermost 0.977

(a) When you toss an unbiased coin five times, what is the probability that you will obtain exactly 3 heads, and 2 tails? (b) In (a), what is the probability that you will obtain exactly 3 heads, and 2 tails, in that order? (c) When you spin an unbiased die, there are six possible outcomes. What is the probability that you spin an unbiased die once, and you get both a 2, and a 6? What is the probability that in one...

Problem 7. Suppose that a coin will be tossed repeatedly 100 times; let N be the number of Heads obtained from 100 fips of this coin. But you are not certain that the coin is a fair coin.it might be somewhat biased. That is, the probability of Heads from a single toss might not be 1/2. You decide, based on prior data, to model your uncertainty about the probability of Heads by making this probability into random variable as wl....
