Answer:
6.8 approximately 7 births/mins
Step-by-step explanation:
3600000/525600
If we have 3600000 births in a year, and in a year we have 6omin * 24hrs*365days a year we therefore, have the equation below
Amount of births in a year / (amount of mins in a year)
= 6.8births per mins
Given the information, we shall proceed as follows:
The given problem is a binomial problem.
n=10 and p=0.48
thus, the probability that the number who consider themselves baseball fans is:
a] exactly five
P(x=5)=10C5(0.48)^5(0.52)^5=0.244
b] at least 6
P(x>=6)=1-P(x<8)
=P(6)+P(7)+P(8)+P(9)+P(10)
=10C6(0.48)^6(0.52)^4+10C7(0.48)^7(0.52)^3+10C8(0.48)^8(0.52)^2+10C9(0.48)^9(0.52)^1+10C10(0.48)^10
=0.1878+0.0991+0.0343+0.0070+0.0007
=0.3289
The answer: 0.3289
c] Less than 6
P(x<6)=1-P(x>=6)
=1-0.3289
=0.6711
The answer is the last option: The associative property of multiplication
