Answer:
yes because 10 groups 27 taking 1 group of 27 is now 9 groups of 27
10*27-27=243 is equal to 9*27=243
Answer:
A) The best way to picture this problem is with a probability tree, with two steps.
The first branch, the person can choose red or blue, being 2 out of five (2/5) the chances of picking a red marble and 3 out of 5 of picking a blue one.
The probabilities of the second pick depends on the first pick, because it only can choose of what it is left in the urn.
If the first pick was red marble, the probabilities of picking a red marble are 1 out of 4 (what is left of red marble out of the total marble left int the urn) and 3 out of 4 for the blue marble.
If the first pick was the blue marble, there is 2/4 of chances of picking red and 2/4 of picking blue.
B) So a person can have a red marble and a blue marble in two ways:
1) Picking the red first and the blue last
2) Picking the blue first and the red last
C) P(R&B) = 3/5 = 60%
Step-by-step explanation:
C) P(R&B) = P(RB) + P(BR) = (2/5)*(3/4) + (3/5)*(2/4) = 3/10 + 3/10 = 3/5

↪LINEAR EQUATIONS..
↪Since the equation given is
↪2x + 3y = 12
↪and the point given is (_,8)
to find the coordinate X or the abssicssa
↪we substitute the value of y = 8
↪therefore. ,, 2x +3 (8) =12
↪=》 2x + 24 = 12 =》 2x = 12-24 =》 2x = -12 =》 x = -6
↪thus , X = -6
↪points = ( -6 ,8)
