Answer:
Total number of marbles = 10+20+30 = 60 out of which 20 are blue.
Probability of first marble being blue = 20/60
Probability of second marble being blue = 19/59
Probability of third marble being blue = 18/58
Probability of fourth marble being blue = 17/57
Probability of fifth marble being blue = 16/56
So probability of all marble being blue when five marbles are drawn from the box = (20/60)*(19/59)*(18/58)*(17/57)*(16/56) = 34/11977 = 0.00283877432

Answer: 60
Step-by-step explanation:
Find the total number of students.
In this case, there are 8 total students. Multiply 60 * 8 = 480
Add all the numbers up.
85 + 65 + 36 + 48 + 75 + 39 + 72 = 420
480 - 420 = 60
x = 60
