Answer:
0.368
Step-by-step explanation:
Number of red marbles= 3
Number of blue marbles= 4
Number of green marbles= 7
Total number of marbles= 3+4+7= 14
Let the first ball is taken out to be red
P(R)=
than again a second ball is drawn, number of balls left= 14-1=13
Number of red= 2
P(R)=
Total probability=
+
Total probability= 0.368
Hence, the correct answer is 0.368

Answer:
23 ) 60 x raised to 3 , y raised 3 , z raised to 3
25 ) 12 p
Step-by-step explanation:
23 ) volume of a rectangular box = l ×b×h
3x square y * 4y square * 5z square x
60 x raised to 3
25 ) area of a square = side × side
(3×4) p
12 p
