Question

Two coins are tossed simultaneously for 360
times. The number of times 2 Tails
appeared was three times ‘No tail appeared
& the number of times ‘1 tail’ appeared is
double the number of times ‘no tail’
appeared. Find the probability of getting
two tails.

Answer 1

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
