Answer:
![\frac{3}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B32%7D)
Step-by-step explanation:
Well, an even decimal die has probability 0.5 of rolling even and 0.5 of rolling odd.
->The chances of rolling exactly one even number on five rolls is
![P(even).(P(odd))^4= 0.5 * 0.5^4 =>0.5^5=>\frac{1}{32}](https://tex.z-dn.net/?f=P%28even%29.%28P%28odd%29%29%5E4%3D%200.5%20%2A%200.5%5E4%20%3D%3E0.5%5E5%3D%3E%5Cfrac%7B1%7D%7B32%7D)
->The chances of rolling exactly three even numbers on five rolls is
![(P(even))^3.(P(odd))^2= 0.5^5*0.5^2=0.5^5=>\frac{1}{32}](https://tex.z-dn.net/?f=%28P%28even%29%29%5E3.%28P%28odd%29%29%5E2%3D%200.5%5E5%2A0.5%5E2%3D0.5%5E5%3D%3E%5Cfrac%7B1%7D%7B32%7D)
The chances of rolling exactly five even numbers on five rolls is![(P(even))^5=0.5^5=> 1/32](https://tex.z-dn.net/?f=%28P%28even%29%29%5E5%3D0.5%5E5%3D%3E%201%2F32)
Further, the probability of independent events is the sum of their probabilities, so the probability of rolling an odd number of even numbers is ![\frac{3}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B32%7D)
Given:
Tom needs to plow 1.1 acres of land.
He can plow 5.5 acres in an hour.
To find:
The time taken by Tom to plow 1.1 acres of land.
Solution:
We have,
Time take by Tom to plow 5.5 acres = 1 hour
Time take by Tom to plow 1 acre =
hour
Time take by Tom to plow 1.1 acres =
hour
=
hour
Therefore, the time taken by Tom to plow 1.1 acres of land is 0.2 hour.
Answer:
7+7, 8+8
Step-by-step explanation:
Answer:
Step-by-step explanation:
In this situation, all of the angles can only be either 108 degrees or 180 - 108 degrees. 180 - 108 = 72 degrees.
So <2 = 108 because it obtuse and corresponding and angle 4 is acute and = 72 degrees.
Answer:
5.8-6.0 range= 0.2
Step-by-step explanation:
The lowest is 5.8 and the highest is 6.0. Subtract the lowest from the highest.
