Answer:

I think C. 0.75

Step-by-step explanation:

MrRoyal

The probability of seeing at least one robin in the next 5 birds is 0.75

How to determine the probability?

The representations are given as:

  • American robins = 0 to 2
  • Dark eye juncos = 3 and 4
  • Song sparrows = 5 and 6
  • Others = 7 to 9

Using the above representations, the numbers that represent an occurrence of seeing at least one robin in the next 5 birds are:

05716 16803 32177 92290 72794 14333 79019 05943 77510 74051 87238 86481 94036 12749 24005

The number of occurrence is:

Number = 15

The number of simulation is 20

So, the probability of seeing at least one robin is:

P = 15/20

Divide

P = 0.75

Hence, the probability of seeing at least one robin is 0.75
