Question

wo coins are tossed simultaneously for 540 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.

Answer 1

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

=180/360

=1 / 2
