Answer: 0.973
Step-by-step explanation:
The probability mass function of geometric distribution is
, 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 

hence, the required probability = 0.973

Step-by-step explanation:
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.
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
