The Patterson family has 3 kids, 1 boy and 2 girls. Suppose that for each birth, the probability of a boy birth is 1/2, and the

elena-14-01-66 [18.8K]

Answer:

$Probability = \frac{1}{8}$

Step-by-step explanation:

Given

Represent Boys with B and Girls with G

$P(B) = \frac{1}{2}$

$P(G) = \frac{1}{2}$

Required

Find the probability or having 1 boy 2 girls

Since the order is not important, the probability is calculated as follows;

$Probability = P(B) * P(G) * P(G)$

Substitute $\frac{1}{2}$ for P(B) and P(G)

$Probability = \frac{1}{2} * \frac{1}{2} * \frac{1}{2}$

$Probability = \frac{1 * 1 * 1}{2 * 2 *2}$

$Probability = \frac{1}{8}$

Hence, the fractional probability is $\frac{1}{8}$

Three numbers are in an arithmetic progression with a common difference of 6. if 4 is subtracted from the first number, 1 is sub

UkoKoshka [18]

Answer:

either of {-9.5, -3.5, 2.5} or {7, 13, 19}

Step-by-step explanation:

Let x represent the first number of the arithmetic sequence. Then the second number is x+6, and the third number is x+12. The geometric sequence is then ...

(x -4), (x +5), 3(x+9)

The common ratio is then ...

(x +5)/(x -4) = 3(x +9)/(x +5)

Cross-multiplying gives ...

(x +5)² = 3(x -4)(x +9)

x² +10x +25 = 3x² +15x -108 . . . . eliminate parentheses

0 = 2x² +5x -133 . . . . . . . . . . . . . . subtract the left side

0 = (2x +19)(x -7) . . . . . . . . . . . . . . factor

x = -9.5 . . or . . 7

The possible original three numbers are ...

{-9.5, -3.5, 2.5} . . or . . {7, 13, 19}
