Answer:
0.292
Step-by-step explanation:
When we select the first widget, there are 20 good widgets from 25 total.
When we select the second widget, there are 19 good widgets from 24 total.
So on and so forth.
So the probability is:
P = (20/25) (19/24) (18/23) (17/22) (16/21)
P = 0.292
Alternatively, we can calculate this using combinations.
We are selecting 5 widgets from a total of 25. ₂₅C₅
From the 5 defective widgets, we want to select 0. ₅C₀
From the 20 non-defective widgets, we want to select 5. ₂₀C₅
So the probability is:
P = (₅C₀ ₂₀C₅) / ₂₅C₅
P = 0.292
Answer:
1:2:2
Step-by-step explanation:
To simplify this ratio, you need to find a common factor to divide by. In this instance, that would be 3.
Answer:
Renting a vehicle when there are 5 cars, 3 vans, and 10 sports utility vehicles available
Step-by-step explanation:
Creating a stuffed animal when there are 6 animals, 3 fur colors, and 12 clothing themes available
This condition requires multiplication or factorials to determine outcomes
Renting a vehicle when there are 5 cars, 3 vans, and 10 sports utility vehicles available
This situation requires the addition counting principle to determine the number of possible outcomes as there is only one car to be picked so all the numbers 10+5+3 = 18 will be added to get the possible outcomes ..
If its talking about the temperature decreased it would be -11 but it's asking for an integer
There should be a typo in the question: the correct formula would be
Let's compute 
first. We have
If we intersect this set with X, we have
So, that would be the left hand side. For the right hand side, we have
And their union is again
