<u>Solution-</u>
Let's assume, the rate of interest of $8000 is x%,
then the rate of interest of $17000 is (x+0.3x) =1.3x%
Interest earned by $8000,
Interest earned by $17,000,
According to the question,
∴ Rate of interest of $8000 is 1.96% and rate of interest of $17000 is (1.3×1.96) =2.55%
Answer: {TH, TT, HT, HH } is the sample space.
Step-by-step explanation:
Since, The sample space is the set of all possible outcomes or results of that experiment.
If a coin is flipped n times then total number of outcomes =
Therefore, When a coin is tossed two times then the total number of the outcomes = = 4
Thus, the set of the sample space must contains 4 elements.
Therefore, {TH, TT, HT} can not be the set of sample space because it only contains 3 element.
{HH, TT} can not be the set sample space because it only contains 2 element.
{TH, HT} can not be the set sample space because it only contains 2 element.
{TH, TT, HT, HH} is the set of sample space because it contains 4 element.
