Probability of rolling exactly 2 odd numbers when a 6 sided die is rolled three times

Mathematics
1 answer:
Dmitrij [34]2 years ago
3 0

Answer:

3/8

Step-by-step explanation:

Probability = Favorable Outcomes / Total Outcomes

There are 3 even numbers and e odd numbers.

P(Even Number) = 3/6 = 1/2

P(Odd Number) = 3/6 = 1/2

Probability it lands twice on an even number and once on an odd number = 1/2 * 1/2 * 1/2 = 1/8

What we must remember here is that the question does not say that the first 2 rolls are even and the 3rd roll is odd.

We must find the number of ways of getting Even, Odd Combinations which are 3!/2! = 3 (EEO, EOE, OEE)

The Required probability = 3 * 1/8 = 3/8

I need the answers to both. Will give brainiest!
miskamm [114]

Answer:

1. Number 1 and 2 and 4 is a function, 2. number 1 is a function

Step-by-step explanation:

1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.

2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.

Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.

Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.

Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.

The vertical test is a way to determine if it is a function.

When looking at a table functions are one-to-one and many-to-one

Non-functions are one-to-many and many-to-many

Hoped this helped you : )
