Respuesta :

"Given that he is male" is an important phrase here. The "given" in any probability problem is often important. This tells us "only focus on the males" because we know 100% that whoever we picked, the person is a male. 

So we only focus on the "male" column. Use a highlighter to mark this column or cover up the other values if they are too distracting. There are 51 males total (bottom row) and 39 males had a flu shot (top row)

Divide the two values: 39/51 = (13*3)/(17*3) = 13/17

Answer: 13/17

The probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male is 13/17 and this can be determined by using the given data.

Given :

The director surveyed 100 randomly selected residents from the college's dormitories to see whether they had received a preventative flu shot.

The following steps can be used in order to determine the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male:

Step 1 - According to the given data, the total number of males is 51.

Step 2 - Also given that the number of males that had a flu shot is 39.

Step 3 - So, the probability that a dormitory resident chose at random from this group has had a flu shot, given that he is male is:

[tex]\rm P=\dfrac{39}{51}=\dfrac{13}{17}[/tex]
