tigry1 [53]

Answer:

probability of there meeting = 15/(60-15) = 15/45 = 0.333 = 33%

Step-by-step explanation:

favorable event = +- 15 minutes

total time they can eat launch is between noon and 1pm = 60minutes

they are both known for non punctuality, that means they cant meet up at 12noon, let assume 15minutes pass noon.

probability of there meeting = 15/(60-15) = 15/45 = 0.333 = 33%

which is probably saying they will not meet for lunch that day.

An animal cage is holding 5 black cats and 8 white cats. None of them want to be in there. The cage door is opened slightly and

nata0808 [166]

Answer:

$\frac{1}{40}$

Step-by-step explanation:

The animal cage contains 5 black cats and 8 white cats.

So the probability of 1 out of 5 black cats escaping can be expressed as $\frac{1}{5}$

The probability of 1 out of 8 white cats escaping can be expressed as $\frac{1}{8}$

The combined probability of 1 black cat and 1 white cat escaping can be expressed as a product of the above two probabilities.

In other words, the combined probability is $\frac{1}{5} * \frac{1}{8}$

$= \frac{1}{40}$
