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:
1
Step-by-step explanation:
Answer:
17 hours 30 minutes
Step-by-step explanation:
Y=1x+5
Take point (2,7) into point slope
Y-7=1 (x-2)
Convert
Y-7= 1x -2
+7 on both sides
Y= 1x + 5
+4 then +6 then +8 then +10 so the answer is 30
