Question

Thirty-three percent of all students at a high school like beef stew. Out of 300 students, 40 are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, what is the probability of a failure for this binomial experiment?

Answer 1

33 40
--- x -----
300 1

Answer 2

do i have to times the numbers

Answer 3

Yes

Answer 4

it gave me a lot of #

Answer 5

Its not just 33 * 40 and 100 * 1. I suggest removing the 0 from 40 and from 300.

33 4 <--- I took 1 zero off so I do the same for 300
--- x -----
30 1

Answer 6

No. If you do, 33 * 4 / 100 you now get 4.4.

Answer 7

How many of the 40 must like it for it to be considered a success? All 40? 1? A majority?

Answer 8

33% of 40

Answer 9

it say 1.32

Answer 10

Ok I get it now, sexy if that is it then it is this;

33 40
--- x -----
100 1

Then subtract the answer from 300 and make it a percent

Answer 11

33 4 132
--- x ----- = -----
30 1 30


132/30 = 4.4

300 - 4.4 = 295.6

Move the decimal point, that is about 29.56% of a failure

Answer 12
