Questions & Step-by-Step Solutions
A jar contains 10 cookies, 4 of which are chocolate chip. What is the probability of selecting a chocolate chip cookie?
Step 1: Identify the total number of cookies in the jar. There are 10 cookies.
Step 2: Identify how many of those cookies are chocolate chip. There are 4 chocolate chip cookies.
Step 3: To find the probability of selecting a chocolate chip cookie, use the formula: Probability = (Number of favorable outcomes) / (Total number of outcomes).
Step 4: Plug in the numbers: Probability = 4 (chocolate chip cookies) / 10 (total cookies).
Step 5: Simplify the fraction 4/10. Both numbers can be divided by 2.
Step 6: The simplified fraction is 2/5.
Probability – The likelihood of an event occurring, calculated as the number of favorable outcomes divided by the total number of possible outcomes.
