<h2>The required probability is 0.1224.</h2>

Step-by-step explanation:

Here, given:

The probability of having 0 dental checkup = 0.3

The probability of having 1 dental checkup = 0.6

The probability of having 2 dental checkup = 0.1

Number of people chosen at random = 7

So, the number of ways 2, 4 and 1 checkup are : $(\frac{7!}{2! \times 4! \times 1!} )$

Now, the combined probability that two will have no checkups, four will have one checkup, and one will have two checkups in the next year

= $(\frac{7!}{2! \times 4! \times 1!} ) \times (0.3)^2 \times (0.6)^4 \times (0.1)^1 = 0.1224$

Hence, the required probability is 0.1224.
