Answer:
2/5
Step-by-step explanation:
markup / cost = 10 /25 = 2/5
Answer: (1/8) (2/8) (3/8) (4/8) (5/8) any of these would work
Step-by-step explanation:
all of these are lower in value in comparison to 5/6
When rolling two standard die there are 36 possibilities.
The smallest sum being 2 (rolling a 1,1) and the largest being 12 (rolling a (6,6).
Of that range, prime numbers are 2, 3, 5, 7, 11.
In the sums there are 1-2's, 2-3's, 4-5's, 6-7's, and 2-11's.
P(sum 2 is die prime) = 15/36 = 5/12
Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58
Then it is in simplest form and they are both prime
