Q. 2.A coin is tossed for a certain number of times. Tthe probability

1.	Q. 2.A coin is tossed for a certain number of times. Tthe probability of getting a head is 0.4 and headappears for 24 times, find the number of times,the coin was tossed. Hence, find probability of1.getting a tail and verify that P(1) + PCT)
Answer» P(H) = 0.4 number of times head came/total number of outcomes = 0.4 Total number of outcomes = 24/0.4 = 60 Number of time tail came = 60-24 = 36 P(T) = 36/60 = 12/20 = 0.6_________________________P(H) + P(T)= 0.4 + 0.6= 1

Q. 2.A coin is tossed for a certain number of times. Tthe probability of getting a head is 0.4 and headappears for 24 times, find the number of times,the coin was tossed. Hence, find probability of1.getting a tail and verify that P(1) + PCT)

Answer»

P(H) = 0.4

number of times head came/total number of outcomes = 0.4

Total number of outcomes = 24/0.4 = 60

Number of time tail came = 60-24 = 36

P(T) = 36/60 = 12/20 = 0.6_________________________P(H) + P(T)= 0.4 + 0.6= 1
