The probability that at least 2 of the dinners selected are pasta dinners will be 0.8181...
<u><em>Explanation</em></u>
Pasta dinners = 7 , Chicken dinners = 6 and Seafood dinners = 2
The student selects 5 of the total 15 dinners. So, total possible ways for selecting 5 dinners 
For selecting at least 2 of them as pasta dinners, the student can select 2, 3, 4 and 5 pasta dinners from total 7 pasta dinners.
So, the possible ways for selecting 2 pasta dinners 
The possible ways for selecting 3 pasta dinners 
The possible ways for selecting 4 pasta dinners 
The possible ways for selecting 5 pasta dinners 
Thus, the probability for selecting at least 2 pasta dinners 
Answer:
<u>(3w + 7)² or (3w + 7)(3w + 7)</u>
Step-by-step explanation:
<u>Identity</u>
- a² + 2ab + b² = (a + b)² = (a + b)(a + b)
<u>Solving</u>
- 9w² + 42w + 49
- (3w)² + 2(3w)(7) + (7)²
- <u>(3w + 7)² or (3w + 7)(3w + 7)</u>
