What is the difference between a graph and a diagram?
The difference between graph and diagram :- Diagram 1) Diagram can be drawn on plain paper and any sort of paper. 2) Diagram is more effective and impressive. 3) Diagram have everlasting effect. 4) Diagram cannot be used as median, mode etc. 5) Diagram can be represented as an approximate idea. Graph 1) Graph can be drawn only on plain paper. 2) Graph is not more effective and impressive. 3) Graph don't have everlasting effect. 4) Graph can be used as median, mode etc. 5) Graph cannot be represented as an approximate idea.

What is the probability of getting 2 girls and 2 boys of 4 children?
It depends. If the order is important, (2 girls then 2 boys): There's a 1/2 chance of any sex, so the probability is 1/16(or 6.25%). But if it's just any order of 2 girls and 2 boys, then it's a different outcome. Consider the following table. The desired outcome is 2 girls, 2 boys in any order. We can just look for 2 girls, and convert to Boolean values of 1 for girl and 0 for boy. Here is the table:0 0 0 0: 00 0 0 1: 10 0 1 0: 10 0 1 1: 2*0 1 0 0: 10 1 0 1: 2*0 1 1 0: 2*0 1 1 1: 31 0 0 0: 11 0 0 1: 2*1 0 1 0: 2*1 0 1 1: 31 1 0 0: 2*1 1 0 1: 31 1 1 0: 31 1 1 1: 4Note each row has five numbers. The first four numbers represent the four children, and the fifth number is a sum of these four numbers. Any time the sum equals exactly 2, then the desired outcome (2 out of the four children are girls).This happens 6 times out of the 16 total possible outcomes, so the probability is 6/16, or 3/8 = 37.5%
