Questions & Step-by-Step Solutions
A box contains 10 chocolates, 4 of which are dark chocolate. What is the probability of randomly selecting a dark chocolate?
Correct Answer: 0.4
Step 1: Identify the total number of chocolates in the box. There are 10 chocolates.
Step 2: Identify how many of those chocolates are dark chocolate. There are 4 dark chocolates.
Step 3: To find the probability of selecting a dark chocolate, use the formula: Probability = (Number of favorable outcomes) / (Total number of outcomes).
Step 4: Substitute the numbers into the formula: Probability = 4 (dark chocolates) / 10 (total chocolates).
Step 5: Simplify the fraction: 4/10 can be simplified to 2/5, or you can calculate it as a decimal: 4 divided by 10 equals 0.4.
Step 6: Conclude that the probability of randomly selecting a dark chocolate is 0.4.
Probability – The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
