Question

probability
a bag contains 36 red, 48 green, 22 yellow, and 19 purple blocks. you choose one block from the bag at random.
expressed as a percent, what is the theoretical probability of choosing a block that is not yellow?
a. 17.6%
b. 82.4%
c. 38.4%
d. 56.0%

Explanation:

Step1: Calculate total blocks

$36 + 48 + 22 + 19 = 125$

Step2: Count non-yellow blocks

$125 - 22 = 103$

Step3: Compute probability as percent

$\frac{103}{125} \times 100\% = 82.4\%$

Answer:

B. 82.4%
