In a sample of 1000 adults, 150 said they are very confident in the nutritional information on restaurant menus. for us adults are selected at random without replacement. find the probability that all four us adults are very confident in the nutritional information on menus

There are 150 confident adults out of 1000.
Selecting four at random withOUT replacement
Probability that all four are confident
=(150/100*149/999*148/997*147/996)
=150!/146! / (1000!/996!)
= 7301/14925090
= 0.00048918

(check: answer < (150/1000)^4=0.00050625, ok)

Step-by-step explanation:

correct Question :A rectangle has a side length and wide of 9 centimeters and 6 centimeters. What is the area of the rectangle Given that :A rectangle has a side length and wide of 9 centimeters and 6 centimeters. to find :area of rectangle. formulas used :A = l × w

where,

A = area of rectangle l = lenth of rectangle W = wide of rectangle explanation :

⟼ l = 9 cm

⟼ W = 6 cm

⟼ Area = l × b

⟼ Area = 9 × 6 cm

⟼ Area = 54 cm².

∴ the area of rectangle is 54 cm².
