If Mickey selects a yo-yo, without looking, from a pail that contains 6 red yoyos, 5 blue yoyos and 4 white yoyos, what is the probability he will pick a blue yoyo? red yoyo? white yoyo?
To find the probability of Mickey picking a specific color of yo-yo, we need to determine the total number of yo-yos in the pail and then divide it by the number of yo-yos of that specific color.
The total number of yo-yos in the pail is the sum of the red, blue, and white yo-yos:
Total number of yo-yos = 6 red yo-yos + 5 blue yo-yos + 4 white yo-yos = 15 yo-yos
Now, let's calculate the probability of selecting a blue yo-yo:
Probability of picking a blue yo-yo = Number of blue yo-yos / Total number of yo-yos
Probability of picking a blue yo-yo = 5 blue yo-yos / 15 yo-yos
Probability of picking a blue yo-yo = 1/3
Similarly, we can calculate the probabilities of picking a red or white yo-yo:
Probability of picking a red yo-yo = Number of red yo-yos / Total number of yo-yos
Probability of picking a red yo-yo = 6 red yo-yos / 15 yo-yos
Probability of picking a red yo-yo = 2/5
Probability of picking a white yo-yo = Number of white yo-yos / Total number of yo-yos
Probability of picking a white yo-yo = 4 white yo-yos / 15 yo-yos
Probability of picking a white yo-yo = 4/15
Therefore, the probability of Mickey picking a blue yo-yo is 1/3, the probability of picking a red yo-yo is 2/5, and the probability of picking a white yo-yo is 4/15.
