Answer:
(a) 3 (b) 1/3
Step-by-step explanation:
The probability is defined as the ratio of number of elements in event to the number of elements in sample space.
(a) As the total number of child is 3, so the number of elements in sample space = 3
(b) The sample space is { boy, boy, girl}
So, the probability is 1/3.
I am not really that great with that but try googling it, it should pop up somehwere, sorry in advance.
<h2>Quick answer :</h2>
<h3>(A) = $4042.50 </h3><h3>(B) = $14520.50</h3>
<h2><em><u>Solution with steps</u></em> : </h2><h2><u>Solution (A)</u> : </h2>
Money invested by a man = $10,500
No.of years for which he invested his money = 7
Rate of interest = 5.5%
We know that :
Principal = 10500
Rate = 5.5%
Time = 7 years
Simple interest the man payed :
Therefore, the simple interest payed by the man = <u>$4042.50</u>
<h2><u>Solution (B)</u> :</h2>
Money invested by the man (principal) = $10,500
The simple interest he payed = $4042.50
We know that :
The amount the man collected after a period of 7 years :
Thus, amount = $14520.50
Therefore the amount he collected after a period of 7 years = <u>$14520.50</u>
