=7/(32+10)÷1/(36×36)×9/(6×9)
=1/6×1296×1/6
=9
The sample space of the experiment (i.e. the total number of ways he can pick 7 random pages out of a total of 6 + 4 = 10 pages) is given by:

If he picks at least 5 pages of maths homework, this means that he either picked 5 pages or 6 pages of maths homework.
The number of ways he can pick 5 or 6 maths homework is given by:

Therefore, the probability that he recovers at least 5 pages of his math homework is given by:
Answer: 152 miles.
Step-by-step explanation: For each hour a train travels 38 therefore if it drove 2 hours it would drive double the distance and so forth.
38 x 4 = 152 miles.
