Answer:

Step-by-step explanation:
Your total is 4 and each one is a individual (1)
so the probability of 1 ball would be :

because the question asks for the probability they are picked 4 times, we would need to multiply ¼ four times.

Answer:
- m∠ABP is 32°,
- m∠ABC is 64°.
Step-by-step explanation:
According to the construction we have:
- BD = BE
- PD = PE
- BP - is common side of triangles BPD and BPE
It gives us:
Then, corresponding angles of congruent triangles are congruent:
So,
- ∠ABP ≅ ∠CBP ⇒ m∠ABP = 32°
Then,
- m∠ABC = m∠ABP + m∠CBP = 32° + 32° = 64°
