Assume that there are 22 frozen dinners: 12 pasta, 6 chicken, and 4 seafood dinners. the student selects 5 of them. what is the probability that at least 2 of the dinners selected are pasta dinners?

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

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
