1/10
Step-by-step explanation:
P(1st marble yellow) = Number of yellow / total
= 2/5
We keep the marble. Now there are four marbles in a bag. Three are green, and one is yellow.
P(2nd marble yellow) = Number of yellow / total
=1/4
P (1st yellow, keep, 2nd yellow) = 2/5 * 1/4
= 2/20 = 1/10
Product A is 17 cents per oz.
Product B is 20 cents per oz.

3. ΔABC ≅ ΔCDA. Reason: HL postulate
Step-by-step explanation:
The two triangles are right triangles (∠B ≅ ∠D = 90°) and one leg (BC, DA) and the hypotenuse (AC, CA) are shown to be congruent. So, the HL postulate applies. The only step needed is to refer to that postulate.
Step 3. ΔABC ≅ ΔCDA. Reason: HL postulate
