Which is a linear graph, and which is a nonlinear graph? How do you know?
Orange is linear; blue is nonlinear
Blue is linear; orange is nonlinear
Both are linear
Both are nonlinear

Blue is linear; orange is nonlinear

Step-by-step explanation:

linear is straight

nonlinear is not

Step-by-step explanation:

There are 26 red (13 hearts +13 diamonds) cards in a pack of 52 cards . Now, 3 cards out of total 52 cards can be selected in C (52, 3) = 52!/3! 49! =22100 no. of ways and 3 red cards out of 26 red cards can be selected in C (26, 3)= 26!/3! 23! =2600 no. of ways. Hence the required probability = 2600/22100 = 26/221 = 2/17.
