Answer:
a.0.0078125
b. 0.1640625
c. 0.0078125
d. 0.0078125
Step-by-step explanation:
To solve this question we can use the binomial probability function:
where
- n is the number of trials in this case the number of children
- k is the number of successes, we can think it as the number of boys
- p is the probability that is a boy
- q is the probability that is a girl,
In this case case p=q
Then
(a) 
(b) 
(c)
(d) 
(a), (c) and (d) are equal as a result of equal probability of giving birth to a boy or a girl. (b) is different because it takes into account the different orders that births can occur
Answer:
4m + 6
Step-by-step explanation:
Hello There!
We can simplify the expression by distributing the 2 to what is inside of the parenthesis ( 3 and 2m)
3 * 2 = 6
2 * 2m = 4m
so the expression 2(3 + 2m) simplified would be
4m + 6
Answer: 1,817 minor earthquakes
Step-by-step explanation: First you make 89.1% and change it to a decimal. You do that by moving the decimal point over 2 spaces to the left. Next you take 16,674 and divide it by 0.891. Once you get that number you subtract 16,674 by your new number from when you divided to get your answer.
