Answer:
In a betting game, you have a bag with red and blue balls. It has a total of 10 blue and 5 red balls. You take randomly 4 of them, one by one (without replacement). If you get more than 1 red balls you win 10 $
Is obtaining 1 or more red balls a dependent or independent event?
It's dependent, if you have 15 balls, and only 5 are red, then the probability of getting a red on the first try is 5/15. Assuming you do not get the red ball, in the second attempt the probability will be 5/14 ... That is, the probability of obtaining a red ball depends on the color of the ball that you have previously obtained.
You roll a dice 10 times and count the number of 5 you get.
Is obtaining 4 by 5 a dependent or independent event?
It's independent
The probability of obtaining a 5 when rolling a die will always be 1/6. Therefore, the probability of obtaining a 5 does not depend on you having obtained it before.
this is a rational number because it can be written as a ratio of two integers
<u>Answer:</u>
The correct answer option is C. P(blue) = 21%.
<u>Step-by-step explanation:</u>
We know that,
the total number of people in a group = 1200
the number of people with brown eyes = 468
the number of people with blue eyes = 252
the number of people with green eyes = 132
the number of people with black eyes = 348
To find the probability of a person with blue eyes to be chosen, we will divide the number of people with blue eyes by the total number of people in the group and multiply it by 100.
P (blue) = × = 21%
The sum of the angles of any triangle is 180°.
75° + 75° + m<BAC = 180°
m<BAC = 180° - (75° + 75°) = 30°
Answer:
Yes, it is possible without brackets
Step-by-step explanation:
First do 2+3 to give yourself another 5
then times this 5 by the original one to get 25
Finally, times the 25 by 4 to get 100
Hope this helps you :)
