<h2>Answer:</h2>

The probability of failure is:

0.5

<h2>Step-by-step explanation:</h2>

It is given that:

Janie flips a coin 70 times and records if it comes up heads.

Also, getting of a head is considered as a success.

This means that getting a tail will be a failure for the experiment.

As we know that for a unbiased coin the probability of getting a tail; and a head are equal.

Hence, the probability of head is: 1/2=0.5

and probability of tail is: 1/2=0.5

Hence, the probability of a failure is: 0.5
