Answer:
5/21.
Step-by-step explanation:
Total number of balls = 7.
Prob(Blue on first pick) = 3/7
Prob(Blue on second pick) = 2/6 = 1/3
So Prob( 2 Blue's) = 3/7 * 1/3 = 3/21 = 1/7.
Prob(Red on first pick) = 2/7
Prob(Red on second pick) = 1/6
So Prob( 2 Red's) = 2/7 * 1/6 = 1/21.
Now the Probability of getting 2 white balls is the same as for the red balls
= 1/21.
Finally, the probability of 2 balls of the same colour
= 1/7 + 1/21 + 1/21
= 3/21 + 1/21 + 1/21
= 5/21.
From the given graph, we can tell kl=lm
therefore,
3x + 2 = 5x - 10
3x+2-2=5x-10-2
subtract 2 from both sides.
3x+ 0 =5x-12
3x=5x-12
3x-5x=5x-5x-12
subtract 5x from both sides.
-2x=0-12
-2x=-12
(-2x)/-2=-12/-2
divide both sides by -2.
1x= 6 -12/-2=6
and of course the -2 and -2 cancel on left side leaving 1x.
x=6
KL = 3x+2 = 20 units
