Question

A coin is tossed 100 times with the following frequencies Head – 45, Tail – 55 the probability for each event is.....

Answer 1

Answer:

(i) Event = {Head}

(i) Event = {Head}n(E) = 55

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100= 11/20

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100= 11/20(ii) Event = {tail}

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100= 11/20(ii) Event = {tail}n(E) = 45

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100= 11/20(ii) Event = {tail}n(E) = 45∴ Probability of event = n(E)/n(S)

(i) Event = {Head}n(E) = 55∴ Probability of event = n(E)/n(S)= 55/100= 11/20(ii) Event = {tail}n(E) = 45∴ Probability of event = n(E)/n(S)= 45/100 = 9/20

Answer 2

Answer:

(i) 45/100 = 9/20

(ii) 55/100 = 11/20

Step-by-step explanation:

(i) The probability of getting a head = 45/100

= 9/20

(ii) The probability of getting a tail =55/100

= 11/20
