Jennifer has a bag containing 40 small one blocks.
there are 20 cubes of which five are blue
there are 20 spheres of which six are blue
Jennifer randomly selects a cube for the bag what is the probability that the cube she selects is blue?
if she knows she gets a cube, then P(blue) = 5/20
What are the answer choices?
. there are no choices 🥲
To find the probability of selecting a blue cube, we need to know the total number of cubes and the number of blue cubes.
Given that there are 20 cubes in total and five of them are blue, the probability of selecting a blue cube can be calculated as follows:
Probability of selecting a blue cube = Number of blue cubes / Number of total cubes
Probability = 5 blue cubes / 20 total cubes
Simplifying further, we get:
Probability = 1/4
Therefore, the probability that Jennifer randomly selects a blue cube from the bag is 1/4.
