Spoints A bag contains 10 blue marbles, 7 red marbles, 2 white marbles and 1 black marble. A marble is chosen. Without replacing the first marble, another marble is chosen. What is the
probability both marbles are blue?

I dont know if I did the correct because it's been a while

Step-by-step explanation:

10 blue

7 red

2 white

1 black

10+7+2+1= 20 marbles in total

100÷20=5% each marble

5×10= 50% chance blue

5×7= 35% chance red

5×2= 10% chance white

5×1= 5% chance black

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
