Answer:
$300
Step-by-step explanation:
In this question, we are simply asked to calculate the simple interest on $3000, at a rate of 20% paid after 6 months.
We can do this as follows. Mathematically, it should be remembered that:
S.I = PRT/100
In this case, we lost out the individual values as follows:
P = $3000, R = 20% and T = 6 months = 0.5years, S.I = ?
We substitute the parameters into the equation:
S.I = (3000 * 20 * 0.5)/100 = $300
P(boy)=1/2
P(girl)=1/2
P(a girl, a boy , a girl and a boy)=1/2*1/2*1/2*1/2= 1/16
P(2 boys and 2 girls ) = 1/[4!/(2!*2!)] =1/6
hope this helps u
