Answer:
-11xy-14y+4x
Step-by-step explanation:
For any birth we have only two possible outcomes either boy or girl. So the chance of getting boy or girl on birth same which is 1/2.
The probability of getting baby boy or baby girl on any birth is
P(Boy) = P(Girl) = 0.5
If a couple has six children then probability that all are boys is
P( all six are boy) = (0.5)^6
= 0.015
The probability that all six are boy is 0.015

Answer: The answer is -22.
Step-by-step explanation:
Our problem is (33-3) ÷ 10-5^2. We can use PEMDAS to solve it.
First, let's eliminate the parenthesis. 33-3 is 30. The problem is now 30 / 10-5^2.
Next, let's get rid of our exponent. 5 to the second power is the same as 5 x 5 which is 25. The problem is now 30 / 10 - 25.
Then, we have to do division before subtraction. 30 / 10 is 3.
Lastly, 3 - 25 is -22.
