Answer:
0.1137= 11.37%
Step-by-step explanation:
Assuming there are 365 days in one year and every people have 1 birthday, then the chance for two people to have the same birthday is 1/365 and the chance they are not is 364/365. We are asked the chance for at least one match among 44 people. The opposite of the condition is that we have 0 matches and easier to calculate. The calculation will be:
P(X>=1)= ~P(X=0) = 1
P(X>=1)=- P(X=0)
P(X>=1)=1 - (364/365)^44
P(X>=1)=1- 0.8862
P(X>=1)=11.37%

Answer:
n = - 1
Step-by-step explanation:
Given
- 8n + 4(1 + 5n) = - 6n - 14 ← distribute and simplify left side
- 8n + 4 + 20n = - 6n - 14
12n + 4 = - 6n - 14 ( add 6n to both sides )
18n + 4 = - 14 ( subtract 4 from both sides )
18n = - 18 ( divide both sides by 18 )
n = - 1
