Answer:

The answer is 0.31

Step-by-step explanation:

We can solve this problem as a binomial distribution function. Probability of selecting business mayors is p=0.4 and selecting non-business mayors is q=0.6.

Then selecting 2 busies mayors out of six is:

[tex]P(x)=combination(6,2)*0.4^2*0.6^4\\P(x)=0.31[/tex]
