Lesson 2: Conditional Probability
Practice 4.2.1: Introducing Conditional Probability
Timothy rolls a pair of number cubes. Use this information to complete problems 1 and 2.
1. What is the probability that both numbers are odd if their sum is 7? What is the probability
that the sum of the numbers is 7 if both numbers are odd?
2. What is the probability that the sum is even if the product is even? What is the probability that
the product is even if the sum is even?
For problems 3 and 4, list the sample space for the given events using a tree diagram and explain what
your symbols represent
. Use conditional probability to determine if events A and B are independent;
show your work
3. Hiro rolls a number cube 3 times.
Event A: The second roll is odd.
Event B: Exactly 2 consecutive rolls are odd.
4. The Millers have 3 children.
Event A: The second oldest is a girl.
Event B: At least 2 are girls.

answer: huh

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
