Hello!
To find how much shelves we cut, we need to divide 9 feet by 3/7 feet. When dividing by fractions, it is like multiplying its reciprocal.
This means that the reciprocal of 3/7 is 7/3.
Therefore, if each shelf is 3/7 feet in length, then there are 21 shelves.
The area of the land is , because it's a square with side 250.
The path forms an inner square whose side are 20 feet less, so the area inside the path is
So, the area of the path is the difference between the outer and inner square:
Answer:
The probability that she rolls a number greater that 4 or a 2 = or 50%
Step-by-step explanation:
Given:
A six sided number cube is rolled labelled from 1 to 6.
To find the probability that she rolls a number that is greater than 4 or a 2.
Solution:
The possible outcomes of rolling a six-sided cube are:
{1,2,3,4,5,6}
Event A:
The favorable outcomes greater than 4 are:
{5,6}
Probability of event A to occur =
Event B:
The favorable outcome is a 2
{2}
Probability of event B to occur =
We find that the two events are mutually exclusive as they have no common outcomes.
Thus, the probability that event A or B occurs ( P(AUB) ) can be given as:
⇒
Since denominators same, so we add the numerators.
⇒
Reducing it to simpler fraction:
⇒ (Answer)
Thus, the probability that she rolls a number greater that 4 or a 2 = or 50%
