Inessa05 [86]
Since we are evaluating, we use PEMDAS so we know the order the operations. Follow PEMDAS:

Original Expression: (-1)8+(-1)7-16-14-(-1)2.

Evaluating: -8-7-16-14+2

-8-7=-15-16=-31-14=-45+2=-43.

The answer is -43 according to PEMDAS.

Please help me on this, I also don't understand what is standard number.
vazorg [7]

Answer:

standard number cube is just a normal dice

So for any designated number 1-6 = (p) = 1/6

Step-by-step explanation:

When there is just one event there will always be 6 possible outcomes for one number, so the number of favorable outcomes will be divided by 6 to get your probability.

A) 2 can occur 1 time. P(2) = 1/6

B) there are 3 even numbers. P(even) = 3/6 = 1/2

C) 4 or 5 are 2 possible outcomes. P(4,5) = 2/6 = 1/3

D) there are 3 odd numbers. P(odd) = 3/6 = 1/2

So for any designated number 1-6 = (p) = 1/6
