Kellie randomly chooses a number from 1 to 10. What is the probability she chooses a number less than 3?A.B.C.D.
Question
Kellie randomly chooses a number from 1 to 10. What is the probability she chooses a number less than 3?A.B.C.D.
Solution 1
Step 1: Identify the total number of outcomes. In this case, Kellie can choose any number from 1 to 10, so there are 10 possible outcomes.
Step 2: Identify the number of favorable outcomes. The question asks for the probability that the number chosen is less than 3. The numbers less than 3 are 1 and 2. So, there are 2 favorable outcomes.
Step 3: The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes.
So, the probability that Kellie chooses a number less than 3 is 2/10 = 0.2 or 20%.
Solution 2
The problem is asking for the probability that Kellie chooses a number less than 3 when she randomly chooses a number from 1 to 10.
Step 1: Identify the total number of outcomes. In this case, Kellie can choose any number from 1 to 10, so there are 10 possible outcomes.
Step 2: Identify the number of favorable outcomes. The problem states that we are looking for the probability that Kellie chooses a number less than 3. The numbers less than 3 are 1 and 2. So, there are 2 favorable outcomes.
Step 3: Calculate the probability. The probability of an event is calculated as the number of favorable outcomes divided by the total number of outcomes.
So, the probability that Kellie chooses a number less than 3 is 2 (favorable outcomes) divided by 10 (total outcomes) = 0.2 or 20%.
Solution 3
Step 1: Identify the total number of outcomes. In this case, Kellie can choose any number from 1 to 10, so there are 10 possible outcomes.
Step 2: Identify the number of favorable outcomes. The question asks for the probability that the number chosen is less than 3. The numbers less than 3 are 1 and 2. So, there are 2 favorable outcomes.
Step 3: The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes. So, the probability that Kellie chooses a number less than 3 is 2/10 = 0.2 or 20%.
So, the answer is 0.2 or 20%.
