Using the binomial distribution, it is found that there is a 0.3438 = 34.38% probability that fewer than 3 of them are boys.
<h3>What is the binomial distribution formula?</h3>
The formula is:


The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, the values of the parameters are given as follows:
n = 6, p = 0.5.
The probability that fewer than 3 of them are boys is given by:

In which:




Then:

0.3438 = 34.38% probability that fewer than 3 of them are boys.

Answer:
   1/3
Step-by-step explanation:
The scale factor is the ratio of image lengths to original lengths.
   B'C' = 1 unit
   BC = 3 units
The scale factor is B'C'/BC = 1/3.
