Answer:
30 small chairs and 24 large chairs
Step-by-step explanation:
Let x and y represent the numbers of small chairs and large chairs built in a day. Then the relations for using available time are ...
20x +50y = 30×60
60x +90y = 66×60
Removing common factors, these can be written in standard form as ...
2x +5y = 180
2x +3y = 132
Subtracting the second equation from the first gives ...
2y = 48
y = 24 . . . . . divide by 2
Using the first equation to find x, we have ...
2x +5(24) = 180
2x = 60 . . . . . . . . . . subtract 120
x = 30 . . . . . . . . divide by 2
The company can build 30 small chairs and 24 large chairs in a day.
The probability to choose letter n is 
. After drawing letter n there left 25 letters and the probability to choose the letter w is 
. After drawing two letters n and w there left 24 letters and then the probability to choose letter b is 
. After drawing three letters n, w and b there left 23 letters, so the probability to choose letter t is 
.
Using the product rule for probabilities, you can obtain that
