Answer:

Daughter age = 3 years

Step-by-step explanation:

Let x be the age of the women and y be the age of the daughter.

Given:

After five year the sum of the women and daughter age = 40

(x+5)+(y+5)=40

At present the sum of the women and daughter age

x+5+y+5=40

x+y+10=40

x+y=40-10

x+y=30--------------(1)

So the sum of the present age is x+y=30

The difference in their present age is 24 years.

x-y=24

x=24+y

Now we substitute x value in equation 1.

(24+y)+y=30

24+2y=30

2y=30-24

2y=6

y=\frac{6}{2}

y=3\ years

Therefore, the daughter age is 3 years.

Answer:

3/50 7/50 40/50

Step-by-step explanation:

Ok. I'm not exactly a math wiz but I think you may be overthinking this. Experimental probability should be the probability from the experiment right. It's in the name. In chemistry if it's a well established value it's called a theoretical value or probability. So the answer should just be the probability from the said experiment. No other funky math terms are given here which clues me to the idea that it might just be this simple.
