A bag contains balls with the numbers 1 through 7 on them. A ball was drawn 165 times. The one ball was drawn 10 times, the three ball was drawn 12 times, the five ball was drawn 7 times, and the seven ball was drawn 9 times. What is the experimental probability of drawing an odd number?

Respuesta :

i think 20% because the even number was called out more than anything else

Answer:

Experimental Probability of drawing an odd number ball is [tex]\frac{38}{165}[/tex]

Step-by-step explanation:

Number of times Ball with 1 number drawn = 10

Number of times Ball with 3 number drawn = 12

Number of times Ball with 5 number drawn = 7

Number of times Ball with 7 number drawn = 9

Total no of time balls drawn = 165

No of time odd numbered ball drawn = 10 + 12 + 7 + 9 = 38

[tex]Probability=\frac{Number\:of\:favorable\:outcome}{Total\:number\:of\:outcome}=\frac{38}{165}[/tex]

Therefore, Experimental Probability of drawing an odd number ball is [tex]\frac{38}{165}[/tex]
