Answer:

Step-by-step explanation:
3rd grade:
Number of girls = 16
Number of boys = 15
Total number of students = 31
4th grade:
Number of girls = 15
Number of boys = 18
Total number of students = 33
Formula for probability of an event <em>E</em> can be observed as:

Probability of picking a boy from <em>3rd grade</em>, 
Probability of picking a boy from <em>4th grade</em>, 
These are two independent events of picking a boy from 3rd grade and 4th grade.
So, probability the captain chooses 2 boys in the first pick can be found by multiplying (1) and (2) above.

Answer:
The paint will not fill the tray by 10.53 cubic inches.
Step-by-step explanation:
We will find the volume of the paint tray and compare it with the volume of the gallon.
Given dimensions are:
Length = 14 inches
Width = 10 inches
Depth = 4 cm or
inches
The volume is given by = length x width x depth
Volume =
cubic inches
Volume of 1 gallon is given as = 231 cubic inches
We can see that volume of 1 gallon is more than volume of tray.
Difference =
cubic inches.
So, the paint will not fill the tray by 10.53 cubic inches.
Well, there are an infinite amount...
1.) 2/5
2.) Multiply 2/5 by anything that equals 1... like 2/2. This will give you 4/10
3.) 6/15
4.) 8/20
etc...
