Answer:
The probability is 2/9
Step-by-step explanation:
Here , we want to find the probability of getting a violet ball first and a pink ball secondly if the violet ball is replaced
probability = number of balls of same color/total number of balls
The total number of balls = (2 + 4) = 6 balls
Probability of selecting a violet = 2/6 = 1/3
Probability of selecting a pink afterwards with replacement = 4/6 = 2/3
So the probability of selecting the balls in that order will be;
1/3 * 2/3 = 2/9
Answer:
a function of your numerical grade
Step-by-step explanation:
because the sentence can not stand on its own
The slope of the line is -1/2
Let the measure of one peice be x
then, the other peice must measure 5x
measure of 1st peice + measure of 2nd peice = total measure of the board
5x + x = 72
6x = 72
x = 12
So, the 1st peice measures x = 12cm
and the other measures 5x = 5 (12) = 60cm.

AB is a straight line and the angle of a straight line = 180°
so that means
