In the game board shown below, the red squares are 1 inch long and 1 inch
wide, the blue rectangles are 1 inch wide and 2 inches long, and the white
squares are 2 inches wide and 2 inches long.
If a table-tennis ball is thrown randomly onto this game board, what is the
probability that it will land on a white square?

A. 40%

B. 37%

C. 58%

D. 23%

A. 40%

Step-by-step explanation:

The area of the total board is 6 in × 10 in = 60 in².

The area of the white squares is 6 (2 in × 2 in) = 24 in².

The probability is therefore 24/60 = 0.4.

6, 15, 24, 33

Step-by-step explanation:

Basically, the number on top of the sigma represents the number of terms total in that sequence, and on the right you have the equation in which you can plug in whichever value that falls into what the top number says to find the output. In other words, just plug in 1 for k to find a1, 2 for k to find a2, etc.

Hope that helps!
