Question

There are five ping pong balls in a bag each one has a number printed on it. The numbers are: {3, 8, 2, 2, 5}. What is the probability that you will select a ball with the number 2 on it? Convert your fraction to a decimal. (Enter your answer rounded to one decimal place.

A) 0.2
B) 0.3
C) 0.4
D) 0.5

Answer 1

C) 0.4

To find the probability of selecting a ball with the number 2, divide the 2 balls with the number 2 by the total 5 balls, resulting in a probability of 0.4.

Step-by-step explanation:

The question asks for the probability of selecting a ball with the number 2 on it from a bag containing ping pong balls with numbers {3, 8, 2, 2, 5}. To calculate the probability, divide the number of favorable outcomes by the total number of outcomes. Here, there are 2 balls with the number 2, and the total number of balls is 5.

The probability (P) is:

P = Number of balls with 2 / Total number of balls = 2/5 = 0.4

So, the probability as a decimal, rounded to one decimal place, is 0.4, which corresponds to option C).
