Cory is a bird-watcher. He estimates that 30% of the birds he sees are American robins, 20% are dark-eyed juncos, and 20% are song sparrows. He designs a simulation. Let 0, 1, and 2 represent American robins Let 3 and 4 represent dark-eyed juncos. Let 5 and 6 represent song sparrows. Let 7, 8, and 9 represent other birds The table shows the simulation results. According to the simulation, what is the probability that at least one of the next five birds he sees is a song sparrow?

A.)0.35
B.)0.2
C0.65
D.)0.5​

Respuesta :

Answer: 0.65

Step-by-step explanation:

the probability is high

The probability that at least one of the next five birds sees is a song sparrow will be 0.65

Probability

Probability is chance that a given event will occur

How to solve this problem?

The steps are as follows:

  • Given,  5 and 6 represent song sparrows
  • Using the above representations, the numbers that represent an occurrence of seeing at least one song sparrow in the next 5 birds are:

05716 16803 96568 33855 76635 88864 05943 77510 74051 97895 86481 94036 24005

  • The number of occurrence is 13
  • The number of simulation is 20
  • Therefore probability of seeing at least one song sparrow will be:

P=(number of occurrence/number of simulation)

∴ P=13/20

∴ P=0.65

There is 0.65 probability that at least one of the next five birds Cory sees is a song sparrow
