Answer:

82.2 %

Step-by-step explanation :

First calculate the normal probability to find the complement.

If the probability of success in a single test is 0.35, then the probability of failure in a single test is 1 - 0.35 = 0.65.

Since there are 4 independent tests and events, the probability that there will be 0 successes of the 4 attempts, is calculated by multiplying it by 4 times, or (0.65) ^ 4 = 0.178.

Not having zero successes, then we automatically know that there must have been at least 1 successful result.

Therefore, if the probability of having 0 successes is 0.178, then the probability of having at least 1 is 1 - 0.178 = 0.822

sería 82.2 % la probabilidad

vivado [14]

Hi there!

Here's the important information we know:

10 lbs of crawfish → 24 oz of seasoning


a) To answer the question in a, you will need to use the cross product method:

10 lbs of crawfish → 24 oz of seasoning

1 lbs of crawfish → X oz of seasoning


24 ÷ 10 = X oz of seasoning

2.4 = X oz of seasoning


Answer a) : This means that 1 lb of crawfish requires 2.4 oz of seasoning.


b) We now know that for 1 lb of crawfish you need 2.4 oz of seasoning, so in order to know how much seasoning you need for 30 lbs of crawfish, you need to multiply 2.4 by 30 :

2.4 × 30 = 72


Answer b): You would need 72 oz of seasoning for 30 lbs of crawfish.


c) We know that for 1 lb of crawfish you need 2.4 oz of seasoning, so in order to know the maximum number of pounds of crawfish that can be cooked with 36 oz of seasoning, you need to divide 36 by 2.4 :

36 ÷ 2.4 = 15


Answer c): You can cook a maximum of 15 pounds of crawfish with 36 oz of seasoning.


There you go! I really hope this helped, if there's anything just let me know! :)
