Exercice n°4: Développer puis réduire A = 8 - 4(x - 3)
B = 2(3 - 4x) + 4(1 - 2x)
C = -2(3x + 1) - 3(x + 3)
D = 5(6x - 1) - (3 + 8x)
E = 2x(x + 4) + X(1 - x)
F = -x(2 - x) + (x2 - 2x) - (3x2 - 4)
G = 3x2 - (x2 - 4x + 5) - 4x(x-3)
H = (2x2 - 7x + 4) - 4x(-3 + 2x)
1 = 5x(-3x - 6) - (- 15x2 + 18x - 6)
pourriez vous me donner la reponse de G​

Asix-sided die of unknown bias is rolled 20 times, and the number 3 comes up 6 times. in the next three rounds (the die is rolled 20 times in each round), the number 3 comes up 6 times, 5 times, and 7 times. the experimental probability of rolling a 3 is 10 %, which is approximately % more than its theoretical probability. (round off your answers to the nearest integer.)
