Chapter 1.1, Problem 30E

To determine

To find:The percentage of female who will get married in the next ten years

Answer to Problem 30E

(e) The conditional distribution of “almost certain” among females.

Explanation of Solution

Calculation:

	F	M
	No.	Percentage	No.	percentage
Almost No chance	119	$\frac{119}{2625}=4.53\%$	103	$\frac{103}{2252}=4.57\%$
Some chance, but probably not	150	$\frac{150}{2625}=5.71\%$	171	$\frac{171}{2252}=7.59\%$
A 50-50 chance	447	$\frac{447}{2625}=17.03\%$	512	$\frac{512}{2252}=22.74\%$
A good chance	735	$\frac{735}{2625}=28.00\%$	710	$\frac{710}{2252}=31.53\%$
Almost certain	1174	$\frac{1174}{2625}=44.72\%$	756	$\frac{756}{2252}=33.57\%$
Total	2625	100%	2252	100%
Percentage	$\frac{2625}{4877}=53.82\%$		$\frac{2252}{4877}=46.18\%$

The percent is part of the conditional distribution of “almost certain” among females.

Conclusion:Therefore, the correct option is (e).
