$\text{Diamonds, spades, clubs and hearts make up the 4 suits of a deck of cards, }$

$\text{which contains 52 cards. There are 13 diamonds in a pack.}$

$\text{Probability of an event:}$

$\text{ Number of favorable outcomes / Total number of outcomes}$

$\text{Probability of getting a diamon}d = \frac{13}{52} = \frac{1}{4}.$

A long distance phone service charges $0.30 for the first 10 minutes and $0.05 for each additional minute or fraction thereof. U

olga nikolaevna [1]

Answer: Our Cost function is discontinuous at every integer after x>10.

Step-by-step explanation:

Since we have given that

For the first 10 minutes , the service charges = $0.30

Let the number of additional minute be 't'.

Amount charge for each additional minute = $0.05

Using the greatest integer function:

So, Cost C of a call in terms of time 't' minutes would be

$C=0.03+0.05\left \lceil t-10 \right \rceil$

As we know that Greatest integer is discontinuous at every integer.

So, our Cost function is discontinuous at every integer after x>10.
