Question

a bag contains 5 blue balls, 4 red balls, and 3 orange balls. if a ball is picked from the bag at random, what is the probability that it is a blue ball? answers have been rounded to the tenths place.

Answer 1

5 / ( 5 + 4 + 3 ) = 41.6%
All the balls make 100% of the balls (12), 5 balls are blue, so you divide 5 blue balls, by 100% of the balls (12) to arrive at the percentage of probability of pulling a blue ball from the bag.

Answer 2

Answer: $41.7\%$

Step-by-step explanation:

Given: The number of blue balls in the bag= 5

The total number of balls in the bag= $5+4+3=12$

If a ball is picked from the bag at random, then the probability that it is a blue ball will be given by :-

$\text{P(Blue)}=\frac{\text{Blue balls}}{\text{Total balls}}\\\\\Rightarrow\ \text{P(Blue)}=\frac{5}{12}=0.41666\approx$

In percent ,  the probability that it is a blue ball =$0.416666\times100=41.666\%\approx41.7\%$

Hence, the probability that it is a blue ball  is $41.7\%$.
