Question

40% students in a certain college are girls and 50% of students are above the median height if two third of the boys are above the median height what is the probability that a random selected student who is below the median height is a girl

Answer 1

Answer:0.6

Step-by-step explanation:

Let total number of students = 100

50% are above the median height.

So the 50 students are above the median height.

And 50 students are below the median height.

Again 40% are girls students. So total number of girls students are 40 and boys are 60.

Two third of boys are above the median height i.e. 40. And that of girls students = 30.

So required probability = 30/50 i.e. 0.6.

Answer 2

Answer:

40% of 100 = 40

100 - 40 = 60 boys

50% above median height

50% below median height
