Answer:

See below ~

Step-by-step explanation:

Question Part I :

⇒ Sample Space = {RR, RY, RR, RR, RY, RR, RR, RR, YR, YR, YR, YY, RR, RR, RY, RR}

⇒ P (One red, one yellow) (for 2 times) = 3/4 × 1/4 = 6/16 = 3/8

============================================================

Question Part II :

⇒ P (one red, one yellow) (for 32 times)

⇒ [P (One red, one yellow) (for 2 times) × 4/4

⇒ 3/8 × 4/4

⇒ 12/32

⇒ 12 times
