Sameer throws , an ordinary die . What is the probability that he throws
2

Text Solution

AI Generated Solution

The correct Answer is:
To find the probability that Sameer throws a 2 when he rolls an ordinary die, we can follow these steps: ### Step 1: Identify the total number of outcomes An ordinary die has 6 faces, numbered from 1 to 6. Therefore, the total number of possible outcomes when rolling the die is: \[ \text{Total outcomes} = 6 \] ### Step 2: Identify the favorable outcomes We need to find the number of favorable outcomes for the event that Sameer rolls a 2. Since there is only one face with the number 2 on it, the number of favorable outcomes is: \[ \text{Favorable outcomes} = 1 \] ### Step 3: Calculate the probability The probability \( P \) of an event is given by the formula: \[ P(\text{Event}) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \] Substituting the values we found: \[ P(\text{rolling a 2}) = \frac{1}{6} \] ### Final Answer The probability that Sameer throws a 2 is: \[ \frac{1}{6} \] ---
