If a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.

Given that a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5.

We are required to find the probability of getting red balls.

Probability=Number of items/Total items

Probability of getting red balls=1-(Probability of getting white balls +Probability of getting black balls)

=1-(3/10+2/5)

=1-7/10

=3/10

Hence if a bag contains white, black and red balls only and the probability of getting a white ball is 3/10 and the probability of a black ball is 2/5 then the probability of getting red balls is 3/10.

Select all the ordered pairs that make this statement true?
Ierofanga [76]

Answer: (24,-9)

(0,9)

(4,6)

Step-by-step explanation:

3x + 4y = 36

Using (3,-2) will be:

= 3(3) + 4(-2)

= 9 - 8 = 1

Using (1,7) will be

= 3(1) + 4(7)

= 3 + 28 = 31

Using (0,0) equals to 0

Using (24,-9) will be:

= 3(24) +4( -9)

= 72 - 36 = 36

Using (0,9) will be:

= 3(0) + 4(9)

= 0 + 36 = 36

Using (4,6) will be:

3(4) + 4(6)

= 12 + 24

= 36

Using (-12,18) will be:

= 3(-12) + 4(-18)

= -36 - 72

= -108

The correct options are (24,-9), (0,9 and (4,6)
