What is the probability of getting heads on onlyone of your

Question

7.You flip a coin three times.

The possible outcomes of this random experiment are,

S = {(HHH), (HHT), (HTH), (THH), (HTT), (TTH), (THT), (TTT)}

n (S) = 8

(a) What is the probability of getting heads on onlyone of your flips?

The cases favorable to the event E1 of getting heads on only one of your flips are,

E1 = {(HTT), (TTH), (THT)}

n (E1) = 3

P (E1) = n (E1) / n (S) = 3/8 = 0.375

(b) What is the probability of getting heads on at least one flip?

The cases favorable to the event E2 of getting heads on only one of your flips are,

E2 = {(HHH), (HHT), (HTH), (THH), (HTT), (TTH), (THT)}

n (E2) = 7

P (E2) = n (E2) / n (S) = 7/8 = 0.875

25. You are to participate in a

Answer 1

These questions are based on probability of getting heads or tall, describe all questions step by step as well as with best examples that would it to be illustrated enlarge. 1. Someone toss a coin 3 times. The probable results of this random testing are, S = {(HHH), (HHT), (HTH), (THH), (HTT), (TTH), (THT), (TTT)} n (S) = 8 (a) What is the possibility of getting heads on only one of your flips? The cases positive to the event E1 of getting heads on only one of your flips are, E1 = {(HTT), (TTH), (THT)} n (E1) = 3 P (E1) = n (E1) / n (S) = 3/8 = 0.375 (b) What is the probability of coming heads on at least one flip? The cases positive to the event E2 of coming heads on only one of your tosses are,
