Answer:
n(B U S) = 75
Step-by-step explanation:
P(E) =
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) =
substitute given values, we will get solution
after cross multiplication , we get
n(BUS) = 0.25 X 300
n(BUS) = 75
Answer:
50
Step-by-step explanation:
Let x represent the number of people that attended the movie.
And y the number of adults that attended the movie
Given;
Percent of adults that attended the movie = 40%
Number of adults that attended the movie y = 20
So,
40% of those that attended the movie area adults.
y = 40% of x
y = 40/100 × x
y = 0.4x
(Ratio of y to x is 4:10 or 0.4)
Making x the subject of formula;
x = y/0.4
Substituting the value of y given;
x = 20/0.4
x = 50
Therefore, 50 people attended the movie.
