If a jellybean is chosen at random from a jar containing 3 blue jellybeans, 8 red jellybeans and 13 green jellybeans, then the probability that the jellybean chosen is red is:
a) 1/2.
b) 1/3.
c) 1/7.
d) 1/8.
e) 13/24.
What is the total number of jellybeans?
How many of those are red?
reduce that fraction to lowest terms
Like I said stop cheating Josh grade 8 is simple
3+8+13 = 24
8 red jellybeans = 8/24
that simplified comes out to 1/3
To find the probability of choosing a red jellybean, we need to determine the total number of jellybeans in the jar and the number of red jellybeans in the jar.
First, let's find the total number of jellybeans in the jar. We add up the number of blue, red, and green jellybeans:
Total number of jellybeans = number of blue jellybeans + number of red jellybeans + number of green jellybeans
= 3 + 8 + 13
= 24
Next, let's determine the number of red jellybeans in the jar, which is given as 8.
Now we can calculate the probability of choosing a red jellybean. Probability is the number of favorable outcomes divided by the number of possible outcomes.
Number of favorable outcomes (red jellybeans) = 8
Number of possible outcomes (total number of jellybeans) = 24
Probability of choosing a red jellybean = Number of favorable outcomes / Number of possible outcomes
= 8 / 24
= 1 / 3
Therefore, the correct answer is b) 1/3.
