Question

What is the estimated probability that at least two of the puppies will be

female?
O A. 5/10 = 50%
O B . 8/10 = 80%
O C. 3/10 = 30%
O'D. 7/10 = 70%​

Answer 1

Given:

The results of the simulation.

Number of puppies = 4

To find:

The estimated probability that at least two of the puppies will be female.

Solution:

Let heads (H) = Female puppy.

Let tails (T) = Male puppy.

The results of the simulation are HHHH, TTTH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH, THTT.

Total outcomes = 10

The results having 2 or more H are HHHH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH.

Favorable outcomes = 8

Now,

`\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}`

`\text{Probability}=(8)/(10)`

Probability in % is

`\text{Probability}\%=(8)/(10)* 100`

`\text{Probability}\%=80\%`

The estimated probability that at least two of the puppies will be female is
`(8)/(10)=80\%.`

Therefore, the correct option is B.
