2 A pail contains one blue block, two green blocks, four yellow blocks, and five purple blocks.
How many yellow blocks would you need to add to the original pail in question 1 to make the probability of drawing a yellow block 1/2? P(yellow) = 1/2
3 A pail contains one blue block, two green blocks, four yellow blocks, and five purple blocks.
If you double the number of blue, green, yellow, and purple blocks, does the theoretical probability of drawing remain the same? Explain. (Yes or No because_______________).
