Answer: Yes, Number of students who study French is greater than number of students who study Japanese.
Step-by-step explanation:
Since we have given that
Number of high school students study Japanese ≥ 100
Percent of high school students who study French also study Japanese = 4%
If the Percent of the students who Japanese also study French = 10%
So, our equation becomes
With the help of ratio, we get that

<u>Given</u>:
Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.
The marbles are selected by not replacing the drawn ones.
We need to the probability of selected a black marble and then a white marble without replacement.
<u>Probability</u>:
Let B denote the black marble.
Let W denote the white marble.
The probability of selecting a black marble is
The probability of selecting a white marble without replacement is
The probability of selecting a black marble and then a white marble without replacement is given by
Substituting the values, we get;
Thus, the probability of selecting a black marble and then a white marble without replacement is
