[Geometric] Find the probability that a person flipping a fair coin gets:

1. the first head on the 4th toss

2.the first head on the 3rd toss

math Statistics-And-Probability

Answer 1

Answer #1

Given,

p=0.5

Here, X is number of trails required to get first head. So X follows geometric distribution.

1)The probability that first head gets on 4th toss

2)The probability that first head gets on 3rd toss

Answer 2

3. Consider a coin-die experiment: One flips a fair coin at first. If he gets a head, then he will roll a 6-sided fair die; otherwise, he will roll a 6-sided unfair die, which has probability to get i faces up (i = i, . . . , 6). If one gets a 2 faces up, what is the probability that he got a tail when he flipped the coin? 2.1

A box contains five coins. For each coin there is a different probability that a head will be obtained when the coin is tossed. (Some of the coins are not fair coins!) Let pi denote the probability of a head when the i th coin is tossed (i = 1, . . . , 5), and suppose that p1 = 0, p2 =1/4, p3 =1/2, p4 =3/4, p5 =1. The experiment we are interested in consists in selecting at random...
