Question

In the sample of $50$ people, $21$ has type $"O"$ blood, $22$ has type $"A"$ blood, $5$ has type $"B"$ blood and $2$ has type $"AB"$ blood. If a person is selected at random find the probability that the person has type $"A"$ blood

• A. $\frac{11}{25}$
• B. $\frac{22}{25}$
• C. $\frac{10}{25}$
• D. None of these

Answer 1

The correct option is A $\frac{11}{25}$

$P(A$ blood) $=\frac{PeopleHavin{g}^{\prime }{A}^{\prime }Blood}{Total}$

$=\frac{22}{50}=\frac{11}{25}$
