Since, there are 22 frozen dinners. Out of these, 22 are pasta, 6 chicken and 4 seafood dinners.
We have to determine the probability that at least 2 of the dinners selected are pasta dinner. At least 2 of the dinners selected are pasta, it means that there can be 2 pasta, 3 , 4 or 5.
So, Probability with at least 2 of dinners
=
We will use the combination formula, which states
=
=
=
= 0.894
=0.90
Therefore, the probability that at least 2 of the dinners selected are pasta is 0.90
