Question

At a carnival, the probability that you chose a winning rubber duck from 30 ducks is 0.20. How many are not winning ducks? The number of ducks that are not winning ducks is

Answer 1

hère is your answer mate...

we know that P(e) +P(not E) =1

there fore P(not E)= 1-0.2= 0.8 ans

and not of dock of not winning ducks are ...no of fav outcomes / total outcomes = 0.8

x/30=8/10

x= 30×8/10 =240/10= 24 answer

Answer 2

Hello....

Here is the answer---

Number of Rubber Ducks = 25 Ducks.

Probability of choosing a winning rubber duck = 0.24

⇒ Probability of not winning the rubber duck = 1 - 0.24

                                                                      = 0.76

Using the Formula,

 Probability of not winning the Ducks

= No. of non - winning Ducks ÷ Total number of Ducks.

⇒ 0.76 = No. of non - winning Ducks ÷ 25

⇒ No. of non - winning Ducks = 0.76 × 25

                                               = 19

∴ Number of non winning Ducks is 19.
