Question

which expression can be used to find the probability that a randomly selected point is in the white area of the grid?
\\( 1 - \frac{9}{16} \\)
\\( 1 - \frac{7}{16} \\)
\\( 1 + \frac{9}{16} \\)
\\( 1 + \frac{7}{16} \\)

Explanation:

Step1: Count total grid squares

Total squares = $4 \times 4 = 16$

Step2: Count blue grid squares

Blue squares = 9

Step3: Calculate white area probability

Probability of white area = $1 - \frac{\text{Blue squares}}{\text{Total squares}} = 1 - \frac{9}{16}$

Answer:

$1-\frac{9}{16}$
