2 )
a) With replacement
Probability of extracting a club is 13/52
Probability of extracting a spade is 13/51
13/52 * 13/51
= 6.37 %
b) Without replacement
13/52 * 13/52
= 6.25 %
3) With replacement
Probability of extracting a ace is 4/52
Probability of extracting a queen is 4/51
4/52 * 4/51
= 0.60 %
b) Without replacement
4/52 * 4/52
= 0.59 %
Answer:
$1600; $2200
Step-by-step explanation:
Simple interest(I) =P×R×T
Where
P=Principal
R=Rate
T=Time
When she is 12 years
P=$1000
R=5%
=5/100
=0.05
T=12 years
Simple interest(I) =P×R×T
=1000×0.05×12
=$600
Total amount=principal + simple interest
=$1000+$600
=$1600
Simple Interest after another 12 years= 24 years
T=24
So,
Simple interest(I) =P×R×T
=$1000×0.05×24
=$1200
Total amount=principal+simple Interest
= 1,000+1,200
=$2,200
