Answer: the correct options are b and d.
Step-by-step explanation:
Let us first define what mutually exclusive events are. If two events are mutually exclusive, it means that they cannot happen at the same time. For example, getting a head and a tail at the same time are mutually exclusive.
Considering a single spin of the spinner, the events that are mutually exclusive are
b)landing on a shaded sector and landing on a 3. This is because 3 is unshaded. You can either land on 3 or an unshaded sector at a time
d)landing on an unshaded sector and landing on a number less than 2. This is because the numbers in the unshaded sectors are greater than 2.
Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.
To Find:
Number of rolls used per wall.
Solution:
Since, we know that the shape of a kitchen is a cuboid.
And a cuboid has total 6 faces, with 4 walls, one roof and one floor.
So, total number of walls in Andy's kitchen = 4
Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.
In order to find the number of rolls used per wall, we'll have to divide the total number of rolls used with the total number of walls.
Number of rolls used per wall =
So, 1.5 rolls are used to cover one wall.

Answer:
<h3>0.1</h3>
Step-by-step explanation:
Probability = expected outcome/total outcome
If a bag contains 3 red balls, 8 blue balls and 11 white balls, then the total outcome will be;
Total outcome = 3 + 8 + 11 = 22 balls
Since we are drawing two balls with replacement;
Probability of drawing red ball = number of red/total outcome = 3/22
Probability of drawing white ball = number of while/total outcome = 11/22 = 1/2
Probability of drawing red first and then white = 3/22 * 1/2
Probability of drawing red first and then white = 3/44
To the nearest tenth, 3/44= 0.1
In percent = 6.8%
