Question

a coin tossed simultaneously for 360 times. The no of times 2 tail appeared was 3 times no tail appeared and the number of times 1 tail appeared is double number of times no tail appeared. what is the probability of two tail appeared​

Answer 1

Step-by-step explanation:

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
