Problem 1. Suppose you roll a fair 20-sided die. Are the following events independent?(a) E₁ is the event that the result of the die roll is even. E2 is the event that the result of the die roll isless than or equal to 6.(b) E₁ is the event that the result of the die roll is even. E2 is the event that the result of the die roll isdivisible by 4.(c) E₁ is the event that the result of the die roll is divisible by 4. E₂ is the event that the result of thedie roll is divisible by 6.(d) E₁ is the event that the result of the die roll is divisible by 4. E2 is the event that the result of thedie roll is divisible by 5.
