A fair dice is rolled 5 times in sequence. what is the probability that you will get exactly the same number for all 5 rollings

1/7776. The probability of you getting any one number when rolling a dice is 1/6. Since you are rolling the dice 5 times and you are trying to get the same number each time. You would multiply 1/6 5-times. 1/6*1/6*1/6*1/6*1/6=1/7776.

Kayleen has been offered two jobs. The first job offers and annual salary of $32000. The second job offers an annual salary of $10000 plus 8% commission on all of her sales. How much money per month would Kayleen need to make in sales to earn enough commission to make more money at the second job?

Answer:

The amount of money he makes in sale to earn enough commission is $22,000 .

Step-by-step explanation:

Given as :

The salary offered for the first job = $32000 annually

The salary offered for the second job = $10,000 annually + 8% per sales commission

Now, let the number of sale make by Kayleen to earn commission to make more money at second job = n sales

Now, According to question

The salary offered for the first job = The salary offered for the second job + 8% of number of sales

Or, $32,000 = $10,000 + 8% of n

Or, $32,000 - $10,000 = ×n

Or, $22,000 = 0.08×n

∴ n =

I.e n = 275,000

So, The amount of money he makes in sale to earn enough commission = 8% of n

I,e The amount of money he makes in sale to earn enough commission = 0.08×275,000

Or, The amount of money he makes in sale to earn enough commission = $22,000

Hence, The amount of money he makes in sale to earn enough commission is $22,000 . Answer
