Assuming number cube has 6 sides
probablity is (desiredoutcomes)/(total possible ouctomes)
since it is 450 times
total possible outcomes=450
experimiental probablity is the one actaully obtained by doing it
theoretical is the predicted amount
so theoretical probablity of rolling a 3 is 1 number out of 6 or 1/6 or 75 times out o 450 times
experimiental is the actaull one so67 out of 450 or 67/450
theoretical is 1/6 or 75/450
experimental is 67/450
Answer:
I need context
Step-by-step explanation:
Answer:
20 elements.
Step-by-step explanation:
Lets say
n(U) = 114
n(A) = 57
n(B) = 79
n(A n B)= 42
Now,
n(A U B) = n(A) + n(B) - n(A n B)
= 57 + 79 - 42
= 94
Now,
n(A U B) compliment = n(U) - n(A U B)
= 114 - 94
= 20
Answer: circle
Step-by-step explanation:
All cross sections of a sphere are circles.
The number of ways that the company can choose four workers is 40920 ways.
<h3>How to calculate the number?</h3>
From the information, the building company employs 3 laborers 12 joiners 8 electrician 4 plumbers. The total number of workers will be:
= 3 + 12 + 8 + 4
= 27 workers
It should be noted that combination will be used to choose the 4 workers. This is illustrated as
Combination formula
ⁿCr = n! / ((n – r)! r!)
n = the number of items.
r = how many items are taken at a time.
where n = 33
r = 4
ⁿCr = n! / ((n – r)! r!)
³³C₄ = 33! / (33 - 4)! 4!
= 33! / 29! 4!
= 33 × 32 × 31 × 30 / 4 × 3 × 2
= 40920 ways
