The probability that a randomly selected student from the class has brown eyes , given they are male

P(\frac{B}{M} ) = 0.3030

Step-by-step explanation:

<u>Explanation</u>:-

Given data

                      Brown           Blue           Hazel           Green

Females           13                  4                  6                   9          

Males                10                  2                 9                   12

<em>Let 'B' be the event of brown eyes </em>

<em>Total number of males n(M) = 33</em>

Let B/M be the event of randomly selected student from the class has brown eyes given they are male

<em>The probability that a randomly selected student from the class has brown eyes , given they are male</em>

<em></em>P(\frac{B}{M} ) = \frac{n(B)}{n(M)}<em></em>

<em>From table the brown eyes from males = 10</em>

P(\frac{B}{M} ) = \frac{10}{33}

P(\frac{B}{M} ) = 0.3030

<u>Final answer</u>:-

The probability that a randomly selected student from the class has brown eyes , given they are male

P(\frac{B}{M} ) = 0.3030
