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:
60
Step-by-step explanation:
to find w:
sin(44) = w/30
w = 30sin(44)
w = 20.8 to 1 decimal place
to find x;
cos(x) = 20.8/45
x = 
(20.8/45)
x = 62.46940334
x = 60
Answer:
<u><em>16 : 2 + 3 </em></u> (remember pemdas)
