What is the probability of tossing an unfair coin 19 times and having heads come up 12 or more times (P(T)=0.7)?
An unfair coin has probability 0.4 of landing heads. The coin is tossed seven times. What is the probability that it lands heads at least once? Round your answer to four decimal places. P (Lands heads at least once) -
An experiment consists of tossing an unfair coin (53% chance of landing on heads) a specified number of times and recording the outcomes. (a) What is the probability that the first head will occur on the second trial? (Use 4 decimal places.) Does this probability change if we toss the coin three times? What if we toss the coin four times? The probability changes if we toss the coin three times, but does not change if we toss the coin...

Tossing a coin 8 times probability of obtaining three heads
Tossing an unfair coin with P(H) = 0.6 and P(T) = 0.4. The coin is tossed 10 times (each toss is independent from others) and in any turn it shows heads, it is tossed again. We want to count the cases where the coin is tossed twice and the second toss, too, is head. For example, H T T T T T T T H T H T In this case, the count will be 1. Only the first turn...
a coin is weighted deliberately so that the probability of tossing heads is twice the probability of tossing tails. what is the probability of tossing three heads in a row? what is the probability of tossing three tails in a row? what is the relative probability of tossing three heads versus three tails?
A coin that comes up heads with probability p is flipped n consecutive times. What is the probability that starting with the first flip there are always more heads than tails that have appeared?
An unfair coin has probability p = 0.20 of being heads and is flipped 100 times. (a) What is the exact distribution, mean, and variance of X the number of heads that appears in this experiments? (b) What is the exact probability that between 15 and 28 heads appear? Please express your solution as a summation. (c) Using the Central Limit Theorem, what is the approximate probability that between 15 and 28 heads appear? Please simplify your solution. (Do not...
probability: please solve it step by step. thanks An unfair coin has probability of heads equal to p. An experiment consists of flipping this unfair coin n times and then counting the number of heads. a. Let Y; be a random variable which is 1 if the ith flip is heads and 0 if the ith flip is tails, where 1 sisn. Show that E (Y) = p and V(Y) = p-p2. b. Derive the moment-generating function of Y. c....
