Step-by-step explanation:
- Create an equation with Austin as x and Jamie as x+69 (I just like workin with addition signs more)= 4(x-3)= x+69-3
- Simplify the equations --> 4x-12=x+66
- Solve the equation: 3x-12=66 --> 3x=78 --> x=26

Answer:
We use the Binomial Distribution where p =.84 then probability will be 0.931.
Step-by-step explanation:
P(X≥ 2) = P(X=2) + P (X=3)
= (³₂)(.84)^2(.16) + (³3)(.84)^3(.16)⁰
≅ 0.931
Hence 0.931 is the answer.
