Genrish500 [490]

Answer:

n(B U S) = 75

Step-by-step explanation:

Explanation:-

<u>Probability</u>:-

P(E) = \frac{number of elements events in E}{total number of elementary events in the random experiment}

P(E) = \frac{m}{n}

Let 'B' be the event of having twelve year old brother

Let 'S' be the event of having twelve year old sister

given data  P(BUS) = 0.25

given total survey  n(survey) = 300

we have to find the value is n(BUS) =?

we will use probability definition we get, P( BUS) =\frac{n(BUS)}{n(survey)}

substitute given values, we will get solution

0.25 = \frac{n(BUS)}{300}

after cross multiplication , we get

n(BUS) = 0.25 X 300

n(BUS) = 75
