Question

How many times would a coin have to show heads in 50 tosses to have an experimental probability of 20% more than the theoretical probability of getting heads? Which of the following represents a function

Answer 1

35 is the Answer

Answer 2

Answer: The required number of heads = 30

Explanation:

Given, Total tosses = 50

The theoretical probability of getting head =
`(1)/(2)`

As per given,

Experimental probability = Theoretical probability + 20% of Theoretical probability

=
`(1)/(2)+(20)/(100)*(1)/(2)`

=
`(1)/(2)+(1)/(10)=0.5+0.1=0.6`

Required number of heads = (Experimental probability) x (Total tosses )

= 0.6 x 50

= 30

Hence, the required number of heads = 30

• A relation is said to be a function if each input value corresponds to a unique output value.

For example: {(1,2), (3,4), (2,3), (4,1))}
