In a certain country, the true probability of a baby being a girl is 0.469. Among the next seven randomly selected births in th

-BARSIC- [3]

Answer:

The probability is 0.995 ( approx ).

Step-by-step explanation:

Let X represents the event of baby girl,

The probability of a baby being a girl is, p = 0.469,

So, the probability of a baby who is not a girl is, q = 1 - 0.469 = 0.531,

Also, the total number of experiment, n = 7

Thus, by the binomial distribution formula,

$P(x)=^nC_x(p)^x q^{n-x}$

Where, $^nC_x=\frac{n!}{x!(n-x)!}$

The probability that all babies are girl or there is no baby boy,

$P(X=7)=^7C_7(0.469)^7(0.531)^{7-7}$

$=0.00499125661758$

Hence, the probability that at least one of them is a boy = 1 - P(X=7)

= 1 - 0.00499125661758

= 0.995008743382

≈ 0.995

If 90 percent of a is 44, what is 30 percent of 3a?

Lesechka [4]

90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...

0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded

what is 30% of 3a.....and we know that "a" is 48.89...

0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer

how to solve this prroblem by marianne buys 16 bags of potting soil that come in 5÷8_pound bags .how many pounds of potting soil

barxatty [35]

So, she buys 16 bags, each of them weights $\frac{5}{8}$ pounds.

to find how many pounds of soil she bought, we have to multiply:

16* $\frac{5}{8}$ =//16 is equal to 8*2, so we can simpify:
2* $\frac{5}{1}$

which is 2*5=10

so in the end she bought 10 pounds of soil!

If p is a true statement and q is false, what is the truth value of p ∨ q?

Dafna1 [17]

$p\lor q$ is true if either of $p$ or $q$ is true. We know $p$ is true, which enough to say that $p\lor q$ is also true.
