Step-by-step explanation:

There are 12 face cards (4 kings, 4 queens, and 4 jacks).

That means 40 cards are not face cards.

The probability that at least 1 of the 5 cards drawn is a face card is equal to 1 minus the probability that all of the cards were not face cards.

P(at least 1) = 1 − P(no face cards)

P = 1 − (40/52)⁵

P = 0.731

The probability is 73.1%.

Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3

Students at an agricultural station conducted a study to compare geneticallymodified (GM) corn with regular corn. Each of 33 plo
OlgaM077 [116]

Answer:

Step-by-step explanation:

The given data is represented in the attachment.

a) Explain why yields from one type of corn are not independent of the yields from the other type of corn.

Yields from one type of corn are not independent of the yields from the other type of corn because, as the corns are planted in two similar plots, they could compete during watering process, even the amount of nutrients shared and the type of air. This means one corn may get more nutrients than the other. Therefore, they are not independent (they are dependent).

b) Based on the summary statistics, GM is expected to more likely obtain yield greater than 123, because 123 is greater than mean for regular corn but less than mean for GM corn.

Thus,

P(yield>123|GM)>0.5; and P(yield>123|Regular)<0.5
