a.
To identify: The probability that she pulls out a blue pen at randomTatyana has 2 blue pens. Two standard number cubes are rolled. What is the probability that the sum is greater than 9 or less than 62 Challenge 2x-1 pens in the pocket of his backpack.
The probability that
Given information:
The total number of pens with
The total number of pens with
Explanation:
Consider the given information.
Objective is to find the probability that
Here, the total number of possible outcomes is
The number of favorable outcomes is 2 because there are 2 blue pens
So, calculate the probability of getting blue pen at random as follows
Therefore, the probability that
b.
To identify:The probability that he pulls out a blue pen at random Samuel has x 3 blue pens.
The probability that
Given information:
The total number of pens with
The total number of pens with
Explanation:
Consider the given information.
Objective is to find the probability that S gets a blue pen at random
Here, the total number of possible outcomes is
The number of favorable outcomes is
So calculate the probability of getting blue pen at random as follows
Therefore, the probability that
c.
To identify:The probability that either Tatyana or Samuel pulls out a blue pen at random.
Given information:
The total number of pens with
The total number of pens with
Explanation:
Consider the given information.
Objective is to find the probability that either
Clearly, the events
So, the probability that either
This can be mathematically expressed as follows
Therefore, probability that either Tor S gets a blue pen at random is
