Answer:

$X = \sqrt{39}$

Step-by-step explanation:

$1)\ X^2 + 5^2 = Y^2\ (Y\ is\ the\ hypotenuse\ of\ the\ smaller\ triangle)$

$2)\ Y^2 + 6^2 = 10^2$

$3)\ X^2 + 25 + 36 = 100$

$4)\ X^2 = 39$

$5)\ X = \sqrt{39}$

If the number of orders at a production center this month is a Geom(0.7) random variable, find the probability that we'll have a

jok3333 [9.3K]

Answer: 0.973

Step-by-step explanation:

The probability mass function of geometric distribution is

$f(x)=(1-p)^{x-1}p,\ \ \ x=1,2,3,...$ , p= probability of success on a trial.

As per given, we have

p=0.7

The probability that we'll have at most 3 orders $P(X\leq3)=P(x=1)+P(x=2)+P(x=3)$

$=(1-0.7)^{1-1}(0.7)+(1-0.7)^{2-1}(0.7)+(1-0.7)^{3-1}(0.7)\\\\=0.7+0.21+0.063\\\\=0.973$

hence, the required probability = 0.973
