The [OH] of vinegar to the  nearest hundredth is 2.82 * 10^-5

<h3>How to calculate the [OH] of a substance:</h3>

The sum of the pH and pOH of a substance is 14. Mathematically

[OH−] = Antilog (pOH)

Given the following parameters

[OH−] = Antilog (9.45)

Substitute

[OH−] = 2.82 * 10^-5

Hence the [OH] of vinegar to the  nearest hundredth is 2.82 * 10^-5

A​ state's recidivism rate is ​22%. This means about ​22% of released prisoners end up back in prison​ (within three​ years). Su
storchak [24]

The probability that both of them go back to prison is 4.48%.

<h3>What is probability?</h3>
  • Probability is a measure of the likelihood of an event occurring.
  • Many events cannot be predicted with total certainty.
  • We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
  • The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

The state recidivism rate is given by 22%.

So, the probability that both of the prisoners will go back to prison will be:

  • = 22% × 22%
  • = 0.22 × 0.22
  • = 4.84%

Hence, the probability that both of them go back to prison is 4.48%.
