Question

Let’s try another one. A bag contains 36 red, 48 green, 22 yellow, and 19 purple blocks. There are 125 blocks in the bag. You choose one block from the bag at random. What is the theoretical probability of choosing a purple block from the bag?

Answer 1

Theoretical probability (TP) is given by:
TP=[Number of favorable (desired) outcomes]/[Total number of possible outcomes]
From the information given:
Number of purple blocks=19
Total number of possible outcomes=125
thus;
TP=19/125
    =0.152
