Question

What is the probability of randomly selecting a person and getting someone who does not have type a blood, given that 32% of people have type a blood?

Answer 1

Given:

32% of people have type A blood.

To find:

Probability of a selecting person that does not having type A blood.

Step-by-step explanation:

Probability can be defined as the ratio of a number of favourable outcomes and a total number of outcomes.

Let the total number of person = 100.

As it is given that 32% of people have type A blood,

`\begin{gathered} 32\%\text{ of 100} \\ (32)/(100)*100=32 \end{gathered}`

So, we can say that 32 out of 100 that having to type A blood.

Now, to find the people that does not have type A blood is:

`100-32=68`

i.e., 68 people do not have type A blood.

So, the probability of selecting a person and getting someone who does not have type A blood:

`(68)/(100)=0.68`

Final answer:

Hence, the required probability value is 0.68.
