Answer: 0.263169
Step-by-step explanation:
Since for every child there is two outcomes (either a boy or a girl), so it is a binomial distribution.
Let x = Number of boys
Given: probability that a child is a boy: p= 0.513
Binomial distribution formula : 
Now, the probability that both children are boys= 
The chance both children are boys = 0.263169
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7
6 minutes because 28/8 is 3.5 that is the number of photos that the printer prints in one minute so you / 21 into 3.5 and that is 6 minutes
Answer:
x∈B
x∈A∪B
x∈A∪C
x∈A∩B
Step-by-step explanation:
As can be seen from the Venn diagram, x is the shaded portion between the intersection of 3 circles A, B and C.
hence x belong to b, and x belong to A union B, x belong to A union C and x belong to A intersection B !
