Answer:
1)The probability that the ball drawn is not red is 6 /14
2)Probability of getting either a prime or a multiple of 3 is 7/10
3)Probability of drawing three balls without replacement such that all three are Same colour is 0.0747
Probability of drawing three balls without replacement such that all three are different colour is 0.5
Step-by-step explanation:
1) A ball is drawn randomly from a bag containing 8 red, 4 blue and 2 green identical balls. Find the probability that the ball drawn is not red.
No. of red balls = 8
No. of blue balls = 4
No. of green balls = 2
Total no. of balls = 8+4+2=14
P(Getting red bal)=
P( ball drawn is not red) =
So,the probability that the ball drawn is not red is 6 /14
2)What is the probability that a number chosen at random from the integers between 1 and 10 inclusive is either a prime or a multiple of 3?
Numbers : 1 ,2,3,4,5,6,7,8,9,10
Prime numbers: 2,3,5,7 = 4
Multiple of 3 = 3,6,9 =3
So, Probability of getting prime number =
Probability of getting multiple of 3 =
So, Probability of getting either a prime or a multiple of 3=
Hence Probability of getting either a prime or a multiple of 3 is 7/10
3)A bag contains four red balls, five blue balls and six green balls. Three balls are drawn from the bag at random without replacement. What is the probability that all three are:
The same colour
Different colour
No. of red balls = 4
No. of blue balls = 5
No. of green balls = 6
Total balls = 15
Case 1 :all three are Same colour
So, probability of drawing three balls without replacement such that all three are Same colour =
So, probability of drawing three balls without replacement such that all three are different colour =
So,probability of drawing three balls without replacement such that all three are Same colour is 0.0747
So,probability of drawing three balls without replacement such that all three are different colour is 0.5
Looking at the graph of the functions, the opposite of the integer represented by point A is 1/10.
My friend's error is that he fail to recognize that the value of Point A is different from Point b on the graph.
<h3>What is opposite integers?</h3>This is known to be the a term that connote a pair of opposite integers which have the negative and positive aspect of a number altogether.
Note that , 4 and -4 are a pair of opposite integers. So,, we can call them opposites due to the fact that they are on the opposite sides of the number line
From the graph attached, you can see that they are not pair because the values of Point B is more than that of Point A because Point A is at one step from 5 while point B is at 2 steps from 5.
Therefore, Looking at the graph of the functions, the opposite of the integer represented by point A is 1/10. My friend's error is that he fail to recognize that the value of Point A is different from Point b on the graph.
