Please help me on this, I also don't understand what is standard number. You roll a standard number cube once. Find P (0)

Please explain to me, thank you

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

Step-by-step explanation:

n + q = 20

.05n + .25q = 3.00

5n + 25q = 300

 n + q = 20

5n + 25q = 300

-5n - 5q = -100

20q = 200

q = 10 quarters

n + 10 = 20

n = 10 nickels

(10 nickels, 10 quarters)
