Let 0, 1, and 2 represent trout.
Let 3 and 4 represent bass,
Let 5 represent perch.
Let 6, 7, 8, and 9 represent other fish.
The table shows the results:

Respuesta :

The estimated probability that at least one of the next four fish Roxanne catches will be a perch is 35%

The probability helps us to know the chances of an event occurring. The probability of Roxanne catching bass is 60%.

What is Probability?

The probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

For the next four of the fishes to be bass, the numbers in the table must contain the digit 3 or 4 in it. Therefore, the cases where Roxanne catches bass are:

  • 2635
  • 2053
  • 4526
  • 6994
  • 4348
  • 3087
  • 8323
  • 3579
  • 3840
  • 6839
  • 3363
  • 7683

Also, it is mentioned that the total number of cases is 20 (Given in the table). Therefore, the probability of catching a bass can be written as,

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Number of cases where Roxanne catches fish}}{\text{Total number of catches}}\\\\\\Probability = \dfrac{12}{20} = 0.60\\\\Probability = 60\%[/tex]

Hence, the probability of Roxanne catching bass is 60%.
