161 1-foot tiles.

EXPLANATION:

To find how many tiles we need,
We must find the area of the kitchen.

To find the area, you multiply
length x width

In this question,
the length is 14
the width is 11.5

14 x 11.5 is 161.

So 161 1-foot tiles to cover the kitchen.

Hope this helps! Have a gud day!

Answer:

C) 0.179

Step-by-step explanation:

Since the trials are independent, this is a binomial distribution:

Recall:

Binomial Distribution --> $P(k)={n\choose k}p^kq^{n-k}$
$P(k)$ denotes the probability of $k$ successes in $n$ independent trials
$p^k$ denotes the probability of success on each of $k$ trials
$q^{n-k}$ denotes the probability of failure on the remaining $n-k$ trials
${n\choose k}=\frac{n!}{(n-k)!k!}$ denotes all possible ways to choose $k$ things out of $n$ things
