Answer:
1/6 - least common - 3/18
1/9 - least common - 2/18
3/18 is equivalent to 1/6
1/9 is equivalent to 2/18
Step-by-step explanation:
Rewriting input as fractions if necessary:
1/6, 1/9
For the denominators (6, 9) the least common multiple (LCM) is 18.
LCM(6, 9)
Therefore, the least common denominator (LCD) is 18.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
1/6 = 1/6 × 3/3 = 3/18
1/9 = 1/9 × 2/2 = 2/18
Answer:
The probability of all three children being girls is 0.125.
Step-by-step explanation:
The events of a boy being born and the girl being born is equally likely.
That is, P (G) = P(B) = 0.50.
The gender of <em>n</em>th baby born is independent of the gender of the (<em>n</em> - 1)th baby born.
Compute the probability of all girls as follows:
P (All three girls) = P (G) × P (G) × P (G)
Thus, the probability of all three children being girls is 0.125.
Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
I think the answer is 3,-7
