4 - 1.5 = 2.5
You must subtract 1.5 from the amount of hours he plays piano, which is 4. This is because he spends 1.5 hours less playing drums than he does playing piano.
Answer:
0.353
Step-by-step explanation:
We have been given that a history class is comprised of 7 female and 10 male students.
We will use combinations to solve our problem.
We can choose 6 female students out of 7 female students in ways.
We can choose 7 male students out of 10 male students in ways.
So the number of ways that 6 female and 7 males can be chose is: 7*120 = 840.
Now let us find ways in which 13 students can be chosen from 17 students as:
Now let us substitute our values in probability formula.
Therefore, the probability of selecting 6 female students and 7 male students is 0.353.
