Question

In tossing a balanced coin, the probability of getting head on its face is twice to the probability of getting tail on its face. The sum of both probabilities (head and tail) is 1.Obtain a pair of linear equation in two variables from the given information.

Answer 1

Hi ,

Let probability of getting head = x

probability of getting tail = y

According to the problem given ,

x = 2y ---( 1 )

x + y = 1 ------( 2 )

Put x = 2y in equation ( 2 ) , we get

2y + y = 1

3y = 1

y = 1/3 ---( 3 )

put y = 1/3 in equation ( 1 ) , we get

x = 2 × 1/3

x = 2/3

Therefore ,

Required equations are ,

x = 2y

x + y = 1

I hope this helps you .
