A couple has 2 children. what is the probability that both are girls if the older of the two is a girl?

1 answer:

7 0

Assuming that the probability of boys and girls is equal (in reality slightly more boys than girls are born), the probability is 1/2, simply because the older girl's gender is given and therefore not a part of the probability.

This question comes from the 'boy or girl paradox', a.k.a. the Mrs Smith Problem.

Somebody help me!! anyone

There are:
2 rectangles with length 11 and height 7
2 rectangles with length 11 and height 6
2 rectangles with length 6 and height 7

So, their areas will be (respectively):
$2(11)(7) = 154m^2$
$2(11)(6) = 132m^2$
$2(7)(6) = 84m^2$

Add all of them up:
$154+132+84 = 370 m^2$

So, your answer is C.
