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

aliina [53]
Jorrel is wrong. 18 shots made out of the 40 shots attempted is 45%. 18 divided by 40 is 45% while 16 shots of him making it would have been a 40% of the shots out of 40 he took.

rodikova [14]

Answer:

Roasted Steak RS=14.47

Grilled Salmon GS= 25.21

Step-by-step explanation:

It's a 2 equation system as follows

E1-> 17RS+14GS=598.95

E2-> 28RS+7GS=581.64

We assume the system has only one solution and apply the following calculation to create a single equation

E3 -> 2x E2 -E1

That way the only incognit will be RS

(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95

39RS= 564,33

We solve for RS and then use E1 to solve for GS and E2 to check the answers
