Question

one person is to be selected at random from of group of 25 people.the probility that seleact person will ne a male is 0.44 and the probility that selected person will be a male who was born after the 1960 is 0.28 r

Answer 1

We have total number of people = 25.

Now, number of mean in the group $= 25 \times 0.44 = 11$

Since the probability of selecting men $= 0.44 = \dfrac{11}{25}$

Similarly number of men born 1960 $= 25 \times 0.28 = 7$

The number of males in the group who were born in 1960 or later $= 11-7 = 4$
