The odds of winning a rifle are 1:9 the probability of winning a carnival game is 0.15 does the raffle or the carnival game give
Lilit [14]

Answer:

Hence the carnival game gives you better chance of winning.

Step-by-step explanation:

Let the event of win be given by 1/10 in the game of rifle then the event of loose is given by 9/10

the

Odds in favor of a game are given by  = P(Event)/ 1- P(Event)

Odds in favor of winning a rifle are given by = 1/10/ 1- 1/10

                                                                         =1/10/9/10

                                                                          =1/9

                                                                             = 0.111

The probability of winning aa rifle game is 0.111

The probability of winning the carnival game is 0.15

Comparing the two probabilities   0.111:0.15

The probability of  winning carnival game is greater than winning a rifle game

0.15>0.11

Hence the carnival game gives you better chance of winning.

Find the greatest common factor of 15x^2 y^3 and -18x^3 yz
AysviL [449]
It should be 3x^2y
I'm using 3 from numbers because 3 is a GCF of 18 and 15
Then I'm getting X^2 because it's the GCF of X^2 and X^3
Then I'm taking y because it's the GCF of y^3 and y
And finally we got no z on the left side so we get 3x^2y
