This is a binomial experiment and you'll use the binomial probability distribution because:
- There are two choices for each birth. Either you get a girl or you get a boy. So there are two outcomes to each trial. This is where the "bi" comes from in "binomial" (bi means 2).
- Each birth is independent of any other birth. The probability of getting a girl is the same for each trial. In this case, the probability is p = 1/2 = 0.5 = 50%
- There are fixed number of trials. In this case, there are 5 births so n = 5 is the number of trials.
Since all of those conditions above are met, this means we have a binomial experiment.
Some textbooks may split up item #2 into two parts, but I chose to place them together since they are similar ideas.
Answer:
<h2><u>
<em>Rei 3 years old</em></u></h2><h2><u>
<em>Sasha 11 Years old</em></u></h2>
Step-by-step explanation:
sasha is 8 years than ei. the sum of their ages is 14. find the ages os sasha and rei
(14 - 8) : 2 = 3 (Rei)
8 + 3 = 11 (Sasha)
------------------
11 + 3 = 14
the answer is good
Trig identity is 509811 negative
Answer:
the minimal number is 3
Step-by-step explanation:
The answer is y=3x.
y=21, x=7
y=mx (m is the variable for slope)
21=m(7)
m=21/7
m=3
