wo coins are tossed simultaneously for 360 times. The number of times ‘2 Tails’ appeared was three times ‘No Tail’ appeared and the number of times ‘1 tail’ appeared is double the number of times ‘No Tail’ appeared. What is the probability of getting ‘Two tails’.
As the number of tosses of a coin increase, the ratio of the number of heads to the total number of tosses will be ½. Is it correct? If not, write the correct one.

Answer:
Two coins are tossed simultaneously for 360 times. The number of times ‘2 Tails’ appeared was three times ‘No Tail’ appeared and number of times ‘1 tail’ appeared is double the number of times ‘No Tail’ appeared. Find the probability of getting ‘Two tails’.
Total number of outcomes = 360
Let the number of times ‘No Tail’ appeared be x
Then, number of times ‘2 Tails’ appeared =3x
Number of times ‘1 Tail’ appeared =2x
Now, x + 2x + 3x =360
⇒ 6x =360
⇒ x= 60
P(of getting two tails)=(3 x 60) / 360 =1 / 2
1/2 is the answer
Answer:
Total number of outcomes = 360
Let the number of times ‘No Tail’ appeared be x
Then, number of times ‘2 Tails’ appeared =3x
Number of times ‘1 Tail’ appeared =2x
Now, x + 2x + 3x =360
⇒ 6x =360
⇒ x= 60
P(of getting two tails)=(3 x 60) / 360 =1 / 2
