Sagot :
If it were like that, 9/20 would be baseball card. [tex] \frac{9}{20} = \frac{x}{60} [/tex]
x=27 since 20x3=60
x=27 since 20x3=60
Answer:
Option D is correct .i.e., Most likely, the number of baseball cards in the deck is 27.
Step-by-step explanation:
we find probability of getting a Base ball card and compare it with probability of Baseball card from whole data.
let,
Total No. of Sports Cards in Data 1= 60
and No. of Base ball card in Data 1 = x
[tex]Probability=\frac{x}{60}[/tex]
In Data2,
Jamie recorded data for 20 times
⇒Total No. of cards in Data 2 = 20
In which 9 cards are of Baseball and 11 cards are of Football.
⇒ No. of Baseball card in Data 2 = 9
[tex]Probability=\frac{9}{20}[/tex]
Now by comparing,
[tex]\frac{x}{60}=\frac{9}{20}[/tex]
[tex]x=\frac{9}{20}\times60[/tex]
[tex]x=9\times3[/tex]
[tex]x=27[/tex]
Therefore, Option D is correct .i.e., Most likely, the number of baseball cards in the deck is 27.
